Is FSX Deluxe w/Accel compatible with Windows 7. I'm looking to get a Dell Studio XPS 7100 desktop
Yes it is. Get a 64-bit versionof Win7 if you can and read the forums concerning tips on installing FSX in Win7. Pay particular attention to posts related to issues with UAC.
I recommend installing FSX in it's own directory and on a seperate drive if possible. Use a short path name such as "D:FSX" and "D:FSX SDK" .
