Solution
Unfortunately, the bit of LabVIEW cannot be checked through property node or invoke node, but there are other ways to check the bit of LabVIEW. When you install LabVIEW,
Get Current LV Bitness.vi is installed in
C:\Program Files (x86)\National Instruments\LabVIEW 20**\vi.lib\Utility and you can see the bit version of LabVIEW through this VI. However, this solution is limited by the version of LabVIEW.
Get Current LV Bitness.vi cannot be found in LabVIEW 2015 or earlier version. So you have to use a Conditional Disable Structure. You will have to configure two different conditions: one that contains code that will run on a 64-bit machine and one that contains code that will run on a 32-bit machine. When you configure the condition, set symbol(s) to TARGET_BITNESS and set Value(s) to either 64 or 32.
Once the conditions are configured, add code to each case. Note that the active case of a Conditional Disable Structure is chosen at compile time. Because of this, the code in the case that applies to the development computer will appear normal, and code in other cases will be inactive and appear faded.
Regardless of the operating system, the executable is running on, the active case depends on the version of LabVIEW that the executable was originally compiled in.
For example, if you put
Get Current LV Bitness.vi in your code and run it with a different bit of LabVIEW, you can see that the corresponding version is denoted.
The above VI is shown in the 32-bit version of LabVIEW 2016.
Get Current LV Bitness.vi is executed in VI, you can see that 32-bit is output.
The above VI is shown in the 64bit version of LabVIEW 2016.
Get Current LV Bitness.vi is executed in VI, you can see 64bit.
Using
Get Current LV Bitness.vi, you will get bit version about whatever bit version of LabVIEW you use.
