I have recently installed Lab Windows CVI 2009 (9.1.0). Certain projects when I go to build them cause CVI to crash. There is no error message or any indication what went wrong. These same projects used to work under Lab Window 8. I have tried re-creating the project and it still causes CVI to crash.
Yes, I can build other projects. It seems related to the installing of ni-visa 5.0.3. I re-installed Lab Windows CVI 2009 and the project would build fine. But I was having issues with ni-visa specifically NI SPY it would start up but always stay minimized no matter what I tried. So I reinstalled NI-VISA, and I had the same issue with building the project. I re-installed Lab Windows CVI and the project will build again. The project that would cause CVI to crash did make use of the VISA libraries. NI-SPY still will not maximize itself.
It's possible there is a problem with the LabVIEW run-time engine that NI Spy runs off of. Try reinstalling the run-time for LabVIEW 2009 SP1 found below.
