I would like to clarify some things for my own benefit as I've decided to clean up my computer and remove a lot of accumulated stuff over the years which includes FS9.I installed a new hard drive and updated my OS to Win 7 Pro. As I understand it from all the other posts regarding installation under Win 7, I should install the program to its' own folder in the new C: drive and not in the "Program files" of Win 7 and turn off UAC during installation.As of this moment, FS9 is installed on the D: drive. So I plan to format that drive and install to that cleaned up drive as well.But I'm wondering, can I do a new install over the existing one one the D: drive and maintain all the sceneries and aircraft and tweaks that I now have, or will everything be disrupted? Is this even a wise thing to do?As always, I appreaciate good help here.Thanks,Jim D.

I'm no computer whiz, but couldn't you defrag your D drive and keep your FS 9 install on it? You'd have to do a clean installon the D Drive, including reinstalling all of your add ons, scenery and tweaks AFAIK. If the D Drive is running OK then couldn'tyou run FS from it already? I'm sure someone more in the know will help you out. :( Alan :(
