reconnecting VB/measurement studio program to an i/o device

[Fritz_Reitz]

I've been asked to "fix" a system wherein a visual basic/measurement studio program controls a NI-9472 i/o device. 

apparently, after doing some microsoft updates, the program no longer communicates with the device.

the program runs, and the 9472 works using the MAX test panels, but the 9472 outputs no longer turn on at the appropriate times in the program's run.

the NationalInstruments.Common.dll/msl/xml files are in a subdirectory of the program's folder, whereas there seems to be an entry in the registry pointing to this same dll in another directory, which I do not seem to be able to edit.

not sure if a reinstallation of the vb software is available, is there a way to re-establish contact between the program and the 9472 otherwise?

Fritz, 

There are a few things you could try:

- Repair your installation of the DAQmx drivers by going to Add or Remove Programs>>National  Instruments software and click Change/Remove.  Then find DAQmx in the window that comes up and click Repair.  You will need the driver disks that you originally used to install DAQmx to do this.  Also, you could try downloading the latest version of DAQmx and installing that. 

- Try running one of the shipping examples (found in the Documents and Settings\All Users\Documents\National Instruments\MStudioVS2005\DotNET\Examples\DAQmx directory)

- Revert you computer back to the restore point that was created before the Windows upgrade to see if this fixes the problem.
