I have a .DLL that uses mscorlib in Labwindows/CVI 2013 SP2. We recently had to update the dotnet from version 4.5.1 to 4.5.2 but in addition to the update, 4.5.1 was scrubbed from the machine. My .DLL is broken now and reports error 17502 when executed from TestStand. Stepping into the CVI code, one of the library function calls is returning a null pointer. This .DLL does work on a machine that always that 4.5.2 on it from the start.
I tried removing both the instrument mscorlib and the function panel(FP). Then reconnecting them. I tried removing the #include and letting the compiler auto add it. I tried adding mscorlib2.fp and making sure I added the mscorlib2 instrument(that is mscorlib version=2.0.0.0). Still not working. I know there is a setting in a labview .ini that tells it which version of dotnet to use. Is there something similar in CVI?
