Thanks, Ashish. No, no drivers were installed. For individual image acquisition devices, drivers are installed, but IMAQHWINFO doesn't need any acquisition devices to run - it *should* just come back "empty."

To add to the confusion, the error 'C:\DOCUME~1\avu\LOCALS~1\Temp\avu\mcrCache7.9\test6_1\toolbox\imaq\imaq\imaqmex.mexw32' refers to a file that I have checked and IS THERE! I can see it in my explorer.

This is very similar to errors that other people have had and posted, but there hasn't been an answer posted anywhere I can find. I emailed someone who had the problem fixed, but they cannot recall the answer, only that it did get fixed in the end.

I think I've run out of places to look, so once more I appeal to the community for any help :)

Thanks,
Tim

Was this problem ever solved? I've been having the same error.
