Description

List all locally installed LabVIEW environments on a Windows 10 machine including the version (xx.x.x) and bitness (x86/x64) of each environment.

 

 

 

This accounts for the Window's registry bitness in Windows 10 that separates HKEY_LOCAL_MACHINE keys to x32 and x64 subkeys.

    x86:  HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\National Instruments\LabVIEW\xx.x

    x64: HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\LabVIEW\xx.x

This also determines the bitness from the executable files directly where:

    x86: "L" -> "PExxL"

    x64: "d" -> "PExxd"

 

How to Use

Run the VI to get a list of all LabVIEW Environments locally installed. The VI also returns the indexes to the current LabVIEW x86 & x64 version. If non exist, the indexes return -1.
