I actually tried this but it didn't work. And I am admin on the system, but even though I checked Run as Admin. I chose Vista 64 as the compatiblity OS selection since Windows 7 is 64 bit too. Didn't work though. I never got an error message but never got a completion either, and I have no folder for the ocr program, Omnipage, in Program Files nor do I have anything in Start.
Can't figure it out.
Try to select XP SP2 for compatibility and see what happens.
My OCR needs are very minimal but I have a version of Abbyy Finereader that came with my Lexmark AIO printer that SEEMS to work pretty well with Windows 7 64 bit even with my Canon LIDE. They have a trial version and the Express version is $50 USD.
