Are you running Win. 7 32 or 64 bit?
Does it crash during the program load process or at some other point in time such as when ProScan attempts to communicate with the scanner?
I would first check that you have all the current Microsoft Windows updates installed.
If you have some time, I would like to try to figure this out. It's always best with email as I like to send debug versions out over a period of a few hours to a few days to narrow these things down.
THANKS Bob!
Your private messages worked and your help is appreciated. I'll spend the next several days playing with ProScan
