At the risk of being overly simple, why wouldn't you use Win 7 drivers? Everything I had running under Win XP runs perfectly under 7 after I used the correct drivers.
"the version of this file is not compatible with the version of windows you're running"
None of my functional software works on 7. I trouble shot, google searched, and driver guided for months and was at an absolute impasse. The dual boot system was the only solution (and my own idea) that I could come up with other than spending thousands on new software and hardware that had been mass produced without being properly tested yet. Windows 7 is garbage (and 5 times larger than xp). Bloatware and poppycock.
