I found this as a location to find the file

Older versions of the drivers installed the files in the  partion in the following directory \Program Files\National Instruments\NI-488.2\Languages\Microsoft C

Newer versions of the drivers (post Vista support) install the files in the \Documents and Settings\All Users\Documents\National Instruments\NI-488.2\Languages\Microsoft C

But when i try to go there i cant get all the way to that directory there are missing folders

I am using M S visual studio 6.0    2005
