When I first got Windows 7 it was a 64 bit machine, and I got caught out by DVC 90 not working. I tried everything I could to make it work. I have an old, but very good scanner from Epson, and it too failed because of the driver, but with a lot of searching I found that providing you over-ruled Windows, you could install a driver for a very similar scanner from Epson that worked perfectly. So I tried this technique for all the Dazzle devices that were available at the time, but none of them would fall for this trick.
I gave up and bought a Dazzle DVD Recorder HD.
