LabVIEW 8.0.1 Readme

February 2006

This file contains important information about LabVIEW 8.0.1, including instructions for mass compiling the LabVIEW 8.0 directory after you install LabVIEW 8.0.1 and changes from LabVIEW 8.0. Refer to the LabVIEW 8.0 Readme for information about known issues and changes from LabVIEW 7.1.

Refer to the National Instruments Web site for the latest information about LabVIEW 8.0.1.

Mass Compiling the LabVIEW 8.0 Directory
Changes from LabVIEW 8.0

Mass Compiling the LabVIEW 8.0 Directory

You must mass compile the LabVIEW 8.0 directory after you install LabVIEW 8.0.1. If you do not mass compile, you will experience unexpected program dialog boxes and degraded performance of LabVIEW. Note: You must have administrator privileges or root access to mass compile the LabVIEW directory.

Complete the following steps to mass compile the LabVIEW 8.0 directory.

1. After you install LabVIEW 8.0.1, launch LabVIEW.
2. The Prompt for Mass Compile dialog box appears.
3. Click the Mass Compile Now button. The mass compile might take a few hours.

• If you install any toolkits or modules with LabVIEW 8.0.1 in the future, you should mass compile the LabVIEW directory again to make sure all the installed VIs are updated to LabVIEW 8.0.1. Refer to the KnowledgeBase for more information about how LabVIEW 8.0.1 affects other toolkits and modules.
• Windows Use the Add or Remove Programs applet in the Control Panel to uninstall LabVIEW 8.0.1. Do not insert the LabVIEW 8.0 CD and select the remove option from the LabVIEW 8.0 installation program because doing so does not properly remove LabVIEW 8.0.1.

Note: Refer to the KnowledgeBase for troubleshooting information if the mass compile fails. You also can refer to the KnowledgeBase for instructions about how to compile the LabVIEW 8.0 directory manually if you click the Don't Ask Me Again button from the Prompt for Mass Compile dialog box and you later need to mass compile the LabVIEW 8.0 directory.
