I am running a 64-bit GUI project using LabWindows 2012 SP1 as a standalone executable. We have the identical program running on two identical computers in our lab, both using Windows 7. Our system administrator recently installed McAfee anti-virus version 8.8 on both PCs and configured some other security settings as well. I am now getting error messages when I try to run the program. One PC immediately pops up an error that says "Mesa.dll could not be found". The error reappears repeatedly if I click on it to try to clear it. The other PC starts the program but gives an error saying "Could not open a session to the VISA Resource Manager" when I try using it to run some other test programs.
Our project ran fine on both PCs until the anti-virus program was installed. On the computer with the DLL error, we have tried uninstalling McAfee, reinstalling the run-time engine, and reinstalling the MS C++ 2008 redistributable. It's still not working.
