How to detect whether LabView is installed

[JacobPaso]

I have an install program for a software package we provide to our customers. During installation, I would like to check if LabVIEW is installed on the system and, if it is, install some LabVIEW VI libraries in the LabVIEw\instr.lib folder.

What is the recommended method of detecting LabVIEW on a PC? For example, looking at a certain registry entry, etc? What is the recommended method of finding the full path to the LabVIEW\instr.lib folder?

Thanks.

HKLM\Software\National Instruments\LabVIEW\Current Version\Path is the key with the path to the newest version of LV installed. The instr.lib folder should be inside that path.
