I am unable to control my instruments using my known good software and a known good GPIB-USB-HS controller. I am using Teststand to call VB6 and VB.NET code which is working on other PCs. I am running Windows 7 and using NI 488.2 version 2.8.
NI MAX identifies the controller and my instruments. I am able to communicate with my instruments through NI MAX. However, the Troubleshooting Utility shows that the software is failing.
The "Help" button provides the following:
Unknown NI-488.2 Software Error
An unknown NI-488.2 software problem has occurred. Try the following to resolve the problem before calling National Instruments:
Restart your system.
Run the NI-488.2 Troubleshooting Utility again.
If you still have the problem, try the following:
Repair the NI-488.2 for Windows software.
Restart your system.
Run the NI-488.2 Troubleshooting Utility again.
Obviously, these steps did not solve the problem.
My software is unable to get a handle to the controller and my function calls do not populate anything in NI-SPY.
I tried installing the latest 488.2 version (3.1.1) which did not help. I tried uninstalling all NI software and then re-installing only the 488.2 software. That did not help either.
Any thoughts?
