> Is it okay to delete the folders under C:\Program Files\National Instruments\LabVIEW 7.1\instr.lib
That would get rid of the files, but it might leave things in the registry.
Use Start => Control Panel => Add or Remove Programs
If your driver is listed in there, use it to remove the program from the registry first.
If the instr.lib files remain after that, then you can delete them.
