How do I completely uninstall NI-VISA? The latest version broke my system.

I've been communicating with a "E4350B Solar Array Simulator" through the NI-VISA that came with LabVIEW for quite awhile, then I decided to install the latest NI-VISA. After that, I cannot communicate with the instrument.

So I uninstalled the following:

1. NI-VISA

2. LabVIEW

3. MAX

Then I reinstalled LabVIEW with its NI-VISA, and it still doesn't recognize my instrument.

I know the instrument can talk, because I have some Matlab code I'm translating over to LabVIEW, and that Matlab code still works perfectly.

Also, Agilent's "Agilent Connection Expert" finds my GPIB device, but LabVIEW is blind to it.

I even tried the GPIB VI in LabVIEW's example-finder, thinking the VISA layer might be the problem; it didn't work either.

Is your GPIB controller made by Agilent? If so you may need to include tulip support to make it work with NI VISA. See this.

Yes, my controller is made by Agilent, and that tulip trick has allowed LabVIEW to see my GPIB device. Thanks!
