−2584 DIAdem could not be started. You must have DIAdem 9.1 Service Pack 2 or later installed to use the DIAdem Report Express VI.
−2580 The Write to Measurement File Express VI cannot append new data to frequency domain waveforms. Frequency domain waveforms are constructed with a base frequency f0 and a delta frequency df. The frequency for a data point is then calculated as f0+N*df. This calculation leads to erroneous results if data is appended to the waveform. This error can occur when you write a frequency domain waveform to a file with Segment Headers set to One header only. Set Segment Headers to One header per segment to correct this error.
1 An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @. If you receive this error while trying to run File I/O VIs, refer to the KnowledgeBase at ni.com for more information.
2 Memory is full. If you receive this error while developing a large application or storing large sets of data in LabVIEW, refer to the KnowledgeBase at ni.com for more information.
4 End of file encountered.
5 File already open.
6 Generic file I/O error. A possible cause for this error is the disk or hard drive to which you are trying to save might be full. Try freeing up disk space or saving to a different disk or drive. Another possible cause for this error is there might be a bad network connection. For example, the network connection is down or a network cable is unplugged.
7 File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct. Another possible cause for this error is there might be a bad network connection. For example, the network connection is down or a network cable is unplugged.

122 The resource you are attempting to open was created in a more recent version of LabVIEW and is incompatible with this version.
123 A timeout occurred.
124 A string contained an unexpected null character.
125 A stack overflow occurred. To correct this error, restart LabVIEW and review your code for recursive data structures.
1000 The VI is not in a state compatible with this operation. This error can occur for several reasons. This error can occur if you attempt to edit a VI that is running or reserved for running. This error also can occur if you attempt to open a reference to a VI that is running or reserved for running. A VI is reserved for running when you open a reference to the VI by wiring a type specifier VI Refnum to the Open VI Reference function, or when you have a Static VI Reference linked to the VI within a running VI. This error also can occur if you try to run a VI using the run method while the target VI is running or reserved for running. To correct this error, ensure the target VI is idle or reentrant. If it is reentrant, use the Open VI Reference function with the options input set to 0x08 to prepare the VI for reentrant run or use the Open VI Reference function with the type specifier VI Refnum wired to a strictly typed VI reference. This error also can occur if you attempt to obtain a VI's image while the VI is being modified programmatically. Wait until the VI is not being modified to get the image of a panel or diagram.
1001 The VI front panel is not open. Use the Window Appearance page to configure if the front panel is shown when the VI is run or loaded. You also can use the Front Panel:Open method to open the front panel programmatically.
1002 The VI cannot run because it has a front panel control in an error state.
1003 The VI is not executable. This error may occur because the VI is either broken or contains a subVI that LabVIEW cannot locate. Select File»Open to open the VI and verify that you can run it. Refer to the KnowledgeBase at ni.com if you receive this error in one of the following situations: while using the VI Server to call a VI dynamically or while building an application.
1004 The VI is not in memory.
1005 VI execution has been disabled in the VI Properties dialog box. Open the Execution page of the VI Properties dialog box to change the settings for the VI execution.

1029 VI Server property is read-only.
1030 VI Reference is already reserved for editing.
1031 VI Reference type does not match VI connector pane.
1032 VI Server access denied. If this error is returned from the Open VI Reference function on a remote connection, use the VI Server page of the Options dialog box to ensure that the VI is exported. If this error is returned from a Property or Invoke Node, the property or method might not be allowed for remote VI Server connections. For example, the Application:All VIs In Memory property is allowed locally, but remotely you should use the Application:Exported VIs In Memory property instead. Refer to the help for the property or method to determine if it is allowed remotely.
1033 Bad run-time menu file version.
1034 Bad run-time menu file.
1035 Operation is invalid for this type of VI.

1090 Specified object cannot be moved.
1091 The VI Server or client received an unrecognized message.
1094 Queue and notifier references of the same name must be obtained using the same data type. When you obtain a reference to a queue or notifier, you can specify which data type the mechanism stores. You can receive this error when future requests to obtain a reference to the same mechanism do not wire the same data type as the original specified data type. Unnamed mechanisms do not have this restriction, because each request to obtain an unnamed mechanism creates a new mechanism. Refer to the KnowledgeBase at ni.com for more information about avoiding this error.
1095 This container cannot be left without a subtype. Right-click the container border and select Replace or drag new subtype.
1096 The Open VI Reference function cannot prepare a non-reentrant VI for reentrant run. Verify the values you wired to the Open VI Reference function.

1098 Cannot disconnect type definitions or polymorphic VIs if the block diagram is not available.
1100 No object of that name was found. No reference could be returned. You can use the Obtain Queue or Obtain Notifier function to look up a queue or notifier by name. If create if not found? is FALSE and a queue or notifier with that name was not found, LabVIEW returns this error.
1102 The string wired to the xml string input is empty.
1103 The XML tag describing the type of data is not recognized.
1104 No end tag was found for an XML start/end tag pair.
1105 An unknown or unexpected XML tag was discovered.
1106 The XML tag describing the type of data does not match the wired type.
1107 The XML enumerated type choice(s) does not match the wired type.
1108 XML value text is illegal or out of range for type and/or format.
1109 Unsupported data type.
1110 No longer used.
1111 Release Semaphore called on a semaphore that was not currently acquired.
1122 Refnum became invalid while node waited for it.
1123 You cannot create an object (such as control caption) in built applications. You must create these objects in the LabVIEW development system.
1124 VI is not loadable.In a built application, this error might occur because the VI being loaded was last compiled for a different OS or with CPU features, such as SSE, that this target does not support. In this case you must rebuild the application for the target OS and make sure SSE compiler settings in the build specifications match the target platform. This error also might occur if the VI is a polymorphic VI, which cannot be loaded in the LabVIEW Run-Time Engine. You must load an instance of the polymorphic VI instead of the polymorphic VI itself.
1125 File version is later than the current LabVIEW version.
1126 VI version is too early to convert to the current LabVIEW version. Refer to the Converting VIs topic in the LabVIEW Help for more information about converting VIs to the current LabVIEW version.
1127 Cannot instantiate template VI because it is already in memory.
1128 Input unit is not compatible with the current unit.
1129 You cannot assign the same numeric value to two or more strings in a ring control. You also cannot assign the same string value to two or more strings in a combo box control. If you receive this error while trying to write to the Strings and Values [] property of a control, refer to the KnowledgeBase at ni.com for more information.
1130 The VI Server connection peer is unresponsive. Refer to the Connection Responsiveness: Check Method topic in the LabVIEW Help for more information about connection polling.
1131 You cannot use this property with this system control.
1135 The tree control's active item is not valid for this property.
1136 You wired an invalid item tag to a tree control property or method.

1147 Cannot insert a remote VI in a subpanel control.
1148 This property is read only while the VI is in a subpanel.
1149 Cannot close or set the state of a closed front panel. The front panel must already be open before you close it or set its state.
1150 Cannot open a front panel that is already open. To set the state of the open front panel, use the Front Panel Window:State property.
1151 Invalid input for front panel state.
1156 Memory full error, possibly due to a data format not matching expected data type. This is caused by trying to allocate a buffer that is too large for memory. Although normal allocation might run the system out of memory, frequently an out of memory error is caused by interpreting the data incorrectly and treating something that is data as the size of the data. Before assuming that the system needs more memory to complete the operation, make sure the read format you are requesting is valid for the data being read.
1157 You cannot use this property with a numeric indicator.
1174 Invalid return parameter for Call Library Function Node. The return type must be Void, Numeric, or String. Numeric return types are passed by value. Strings return types are passed as a C String Pointer or a Pascal String Pointer.

1358 The splitter bar cannot be moved to this position because it violates the minimum or maximum size of a descendant pane. When LabVIEW tries to move the splitter bar to the specified position, at least one pane shrinks smaller than its set minimum size. For example, if you have a VI with one vertical splitter bar, and the minimum size of the left pane is 50, wiring 10 to the Splitter Position property will return this error. To correct this error, set the minimum size of the pane to a smaller value, or wire a value to the Splitter Position property that does not shrink the pane beyond its minimum size.
1359 A drag cannot start because a previous drag transaction is still pending.
1360 Cannot provide the type of data requested for this drag and drop operation. To correct this error, ensure that a drag and drop operation is in progress when you call this function and that the data type and drag data name match what is currently available during the drag and drop operation.
1361 The name or data type of a drag data element conflicts with the built-in LabVIEW drag data types. You cannot use the prefix LV_ on a data name.
1362 Cannot use this property with this string display mode or if word wrapping is enabled. Change the display mode to 0 (normal) and/or disable word wrapping to use this property.
1363 The specified name or GUID is invalid.
1364 The provider plug-in is not installed or somehow corrupt.

1378 Cannot set the Active Frame property on a Conditional Disable structure. This error occurs when you try to use the Active Frame property with a Conditional Disable structure. You cannot use this property with a Conditional Disable structure because conditions determine the active frame. You can use this property only with a Diagram Disable structure.
1380 License checkout failure. Unable to checkout the requested license feature because the license is invalid or does not exist.
1381 Cannot create semaphores with a size less than one.
1384 Cannot start dragging because duplicate names for drag data types were passed to the Start Drag method or Drag Starting? event. To correct this error, ensure that the names you use for drag data are unique in each element of the data array for the method or event.
1385 Cannot start a drag and drop operation because the data provided is invalid. To correct this error, verify that the drag data array is not NULL and that all elements have names and data fields.
1388 The block diagram you are attempting to access belongs to a VI that is either in evaluation mode or has an invalid license. To correct this error, you must obtain a valid license for the VI and its containing library.
1389 You are attempting to save or copy a VI that is either in evaluation mode or has an invalid license. To correct this error, you must obtain a valid license for the VI and its containing library.
1390 You attempted to open a VI Server reference to an out-of-scope VI. A VI can open VI Server references only to other VIs that it could call as subVIs. After the reference is opened, that VI can return the reference to other VIs that could not normally open the reference.
1396 Cannot convert text from the source character set to the destination character set.
1397 You have not wired a required input on this subVI. To correct this error, wire the required input.
1398 The subVI cannot be inlined because there is a local variable in the block diagram.
1399 The subVI cannot be inlined because a front panel terminal is not on the root diagram. For example, this error might occur when a front panel terminal is inside a structure.
1430 The path is empty or relative. You must use an absolute path.
1432 The specified format cannot be used with floating point data. For example, hexadecimal notation is not a valid format for floating point numbers.
1434 The precision is greater than the maximum allowed value for this format.
1436 Numeric precision cannot be negative.
1438 Archive version is later than the current LabVIEW version.
1439 A project library cannot be copied to the same folder as the original library because the new library files would conflict with the original library files on disk. You must specify a different location on disk when copying a project library.
1440 The filename does not match the expected name. The file specified must have the same filename as the original file.
1443 Debug connection refused by specified server. Only one debug connection is allowed per application or shared library.
1444 No VIs to download from application, connection closed.
1445 Open VI Reference no longer matches VIs in memory by filename. A filename is no longer sufficient because the full name of a VI now includes any owning libraries. You can use the Strip Path function to wire the filename as a string, but this will not work for VIs in libraries.
1447 There was a name conflict while saving for previous. VIs in libraries are saved in the form LIBRARYNAME_VINAME. There is already a VI in this hierarchy with this name.
1449 Arrays must have at least one dimension and a maximum of 63 dimensions.
1450 One or more untitled library dependencies exist. This file cannot be saved until all dependent files have been named.
1451 One or more untitled dependencies exist. This file cannot be saved until all dependent files have been named.
1452 This library was saved in an earlier version of LabVIEW. It must be loaded and saved in the current version of LabVIEW.
1453 You may only set the vertical arrangement on a label, caption or free label.
1454 LabVIEW classes cannot be flattened as XML in this version of LabVIEW.
1455 Revert failed. This item has been edited in another context on this machine. Only that instance can be reverted.
1468 Specified ability not supported by the library. Verify the ability name does not contain spaces.
1469 Specified ability already exists. You cannot add an ability multiple times.
1470 Specified folder is outside the library. You cannot add library items to folders that do not belong to the library.
1483 Cannot change width of the plot legend when you configure the plot legend to automatically resize, or if the legend has more than one entry and you arrange the plot legend horizontally. Right-click the graph or chart and deselect Autosize Plot Legend in the shortcut menu to disable automatic resizing and make sureyou arrange the plot legend vertically.
1484 LabVIEW cannot inline the subVI into its calling VIs because the block diagram of the subVI contains an implicit control reference. To correct this error and inline the subVI, remove the implicit control reference.
1485 LabVIEW cannot inline the subVI into its calling VIs because the block diagram of the subVI contains an implicit Property Node or Invoke Node. To correct this error and inline the subVI, remove the implicit Property Node or Invoke Node.
1488 The migration file cannot load because it is no longer supported.
1489 The migration file cannot load because its content is not valid or is corrupt.
1490 The migration file cannot load because it makes references to data that does not exist or is invalid.
1491 If you obtain a queue reference in one application instance, you cannot use that queue reference in another application instance. You cannot use queues for communication between LabVIEW application instances.
1492 If you obtain a notifier reference in one application instance, you cannot use that notifier reference in another application instance. You cannot use notifiers for communication between LabVIEW application instances.
1493 The save operation failed because multiple files of the same name cannot be saved into a single LLB. To correct this error, save to a folder instead of an LLB.
1497 Cannot unlock a library for edit when instances in running VIs exist.
1498 Library has errors. Fix the errors before attempting this operation.
1499 Library has edits in another context. Sync up changes before attempting this operation.
1500 If you obtain a user event reference in one application instance, you cannot use that user event reference in another application instance. You cannot use user events for communication between LabVIEW application instances.
1502 Cannot save a bad VI without its block diagram.
1503 Cannot save a clone of a reentrant VI.
1504 Cannot save a remote panel.
1517 An error occurred in the Call Library Node processing. This error was most likely a configuration mismatch between the calling conventions of the Call Library Node and the function being called in the DLL.
1523 Passed an invalid number of strings to the Strings [ ] property. You must pass either 1 string or 6 strings.
1524 The target version for save is not formatted correctly. The target version for save must be a valid LabVIEW version in the form x.x or xx.x, where x is a number. Refer to the LabVIEW Help for a list of valid versions.
1526 This property does not apply when the plot legend of a graph or chart is in tree view.
1529 There are too many nested VI calls. This typically results from recursion without a proper termination condition to stop the recursion.
1532 The target application instance is currently being destroyed. You cannot get a new reference to the application instance or load a VI in the application instance.
1533 A shared variable node cannot be created from the specified terminal.
1534 The semaphore you specified does not exist. LabVIEW cannot return a reference to the semaphore. This error might occur if the create if not found input of the Obtain Semaphore Reference VI is FALSE and LabVIEW cannot find a semaphore with the name you specify.
1535 The semaphore reference you specified is invalid. To correct this error, make sure the reference to the semaphore is valid.
1544 LabVIEW attempted a read, write, or seek on a file opened in unbuffered mode, and the data size is not a multiple of the disk sector size. Use the Get Volume Info function to return the proper sector size. If you do not have the right amount of data to align to a sector size, you must pad the data with filler data and delete the filler data before LabVIEW reads back the file.
1545 LabVIEW attempted to read or write data to a file opened in unbuffered mode, and the data is not aligned properly. LabVIEW determines how data is aligned and you cannot alter that alignment. If this error occurs, you must enable buffering and reopen the file.
1546 The VI must be in a project to use this property.
1548 Queue refnum cannot be obtained with a size of zero. Size input must be a positive number or -1 for unlimited size.
1550 The license for the I/O server type is invalid.
1553 The LabVIEW Run-Time Engine cannot load the polymorphic VI. This error occurs in stand-alone applications when the VI is polymorphic. To correct this error, load an instance of the polymorphic VI rather than the polymorphic VI itself.
1554 The current LabVIEW target cannot load control VIs.
1556 The reference is invalid. This error might occur because the reference has been deleted.
1557 LabVIEW tried to access duplicate references at the same time.
1558 There is a type mismatch between the wire type and the internal data type of the reference. This problem might occur due to a type cast error.
1564 Project file cannot be saved at this time. The project has a locked untitled dependency. The lock prevents giving the untitled item a name so it cannot be saved.
1571 You cannot open a packed library saved in a version earlier than the current version of LabVIEW.
1573 You cannot load a packed library built for a target or operating system different than the current target or operating system.
1574 Cannot open a file with separated compiled code in the LabVIEW Run-Time Engine. Contact the distributor of the file. The distributor must include compiled code in the file for it to run in the LabVIEW Run-Time Engine.
1579 Specified paths do not share a common directory. The paths must share a directory. Consider building caches for each set of paths that share a common directory.
1580 Cannot find the compiled code in the compiled object cache. Verify that the VI is marked to save its compiled code separately and that it is not broken. Then compile the VI.
1581 Cannot use this property on either .NET or ActiveX Container.
1584 The data in the reference cannot be resized. There is a size mismatch between the data in the reference and the data wired to the Data Value Reference Write Element border node.
1586 Compiled code is out of date.
1587 VI is not marked to separate compiled code from source file.
1588 Compiled object cache is corrupt.
1590 The qualified name of one of the dependencies of the specified file is not what LabVIEW expected. This mismatch implies that the dependency report is unreliable, so the ReadLinkInfo operation was aborted.
1595 The RT target does not have enough memory to load the startup application.
1596 Cannot use SSL on this operating system because SSL is either not configured, not installed, or not supported.
1597 The Paste Data operation attempted to paste data into a destination that would have had a dimmed 'paste' option in the shortcut menu.
1599 An empty string is not a valid method name.
1603 The Open VI Reference function does not support using an asynchronous call by reference option with the Prepare for reentrant run option. Both the 0x80 and 0x100 option flags conflict with the 0x08 option flag. The 0x08 flag is useful when running VIs with the Run VI method. The 0x08 flag is not useful when performing asynchronous calls. To correct this error, remove either the 0x08 option or the 0x80 and 0x100 options.
1604 The Open VI Reference function does not support using the option 0x08 (Prepare for reentrant run) with the asynchronous call by reference options 0x80 (Prepare to call and forget) or 0x100 (Prepare to call and collect).
1611 An internal error occurred because a front panel item has no execute data. Recompiling the VI may fix this issue.
1616 The path to save the report is not valid. A valid path cannot contain any of the following characters: (Windows) < > / | : " * ? or (OS X/Linux) < > \ | : " * ?.
1617 LabVIEW is unable to generate a VI comparison report. Make sure you have write permission to the path you specified and generate the report again.
1619 LabVIEW is unable to find the Microsoft Word components. Make sure you installed Microsoft Word correctly.
1620 LabVIEW is unable to create the Microsoft Word report. Try generating the report again. If the problem persists, contact National Instruments technical support.
1621 LabVIEW is unable to create the Microsoft Word report. Try generating the report again. If the problem persists, contact National Instruments technical support.
1622 LabVIEW is unable to create the Microsoft Word report. Make sure you installed Microsoft Word correctly and create the report again.
1623 LabVIEW is unable to find the Microsoft Word components. Make sure you installed Microsoft Word correctly.
1624 You can only generate web page or plain text reports on OS X and Linux.
1627 The control index at position %d is invalid.
1628 LabVIEW cannot convert the input data type at position %d to the control data type.
1629 The control must have a terminal on the block diagram..
1630 If you wire a variant or a LabVIEW class library file (.lvclass) to this function, you must call the function on a VI in the same application instance.
1632 You cannot insert a custom control directly into a subpanel. Use a VI with the custom control on its front panel instead.
1640 Channels are incompatible with asynchronous call by reference options 0x80 (Prepare for call-and-forget) and 0x100 (Prepare for call-and-collect). Channels currently express only intraprocess communication. Channels cannot maintain their state properly if one endpoint or the other shuts down independently. Both of the asynchronous call modes Prepare for call-and-forget and Prepare for call-and-collect allow the called VI to have a different run lifetime from its direct caller.
4800 Selected Device is Invalid The currently selected device index is invalid. This could be caused by an invalid sound driver.
4801 Invalid sound task refnum. No sound driver is available for use, or the given GUID is not a valid DirectSound device ID.
4802 The sound device is busy. Another application is currently using the device. Raising this application's priority level could resolve this issue.
4803 The sound driver or card cannot accommodate the specified configuration. Check that the parameters entered are within the supported range for the hardware and drivers. If you receive this error while using the Sound Output Configure VI, refer to the KnowledgeBase at ni.com for more information.
4804 Cannot write in file playback. The application attempted to write to the file while it was being played. This error code is not currently reported by the LVSound library.
4805 Could not find the sound file. The specified sound file could not be found.
4806 DirectX 8.0 or higher is required to run. To correct this error, install the latest version of DirectX from http://www.microsoft.com/downloads.
4810 Cannot recognize sound format. The sound format of this file is not recognizable. The file may be corrupt.
4811 Cannot support sound format. The specified wave format is not supported. This could be a limitation of the hardware, driver, or both.
4820 A buffer underflow has occurred. A buffer underflow has occurred because the application is not writing data quickly enough.
4821 Overwrite error. An overwrite error has occurred because the application is not reading data quickly enough from the buffer.
4822 A timeout occurred before the operation finished. A timeout error occurred because the application was unable to successfully acquire a mutex.
4823 You cannot perform this operation without an active task. Ensure that a task is active and try again. An input task might stop running if the input buffer overflows. Overflow occurs when the data is not read fast enough.
56000 Generic project error.
56001 An item with this name already exists in the project.
56002 An item with this path already exists in the project.
56003 Adding this item would cause a conflict with another item.
56004 The project item could not be found.
56005 The item type is not compatible with the target type.
56006 You cannot add a packed library to a project library.
66464 The global time on the controller was altered, which might affect the period of an iteration of the NI Scan Engine. A timing source such as IEEE-1588 or GPS modified the global time value on the controller. This can result in a temporary phase shift, which would alter the update period for NI Scan Engine variables for one iteration.
