Hi,Currently I'm using Windows 7 64-bit with FSX, the rare CTD every now and then, and constant CTD's with the PMDG MD-11. (It's been about 3/4 of a year since I last flew the MD-11 on a flight; I can't run it at all). I have heard here and elsewhere that it is better to install FSX clear of the Microsoft Games folder. I installed it in the MS Games folder before I knew about this. Would Cutting and pasting the folder into C drive be an option, or do I have to reinstall FSX to move the folder location?Any help would be greatly appreciated.

You need to uninstall then reinstall.

Cut n paste is no problem - once it's moved go to Flight1 and download their Flight1 Registry Tool to fix the path.Get it from here:-http://www.flight1.com/view.asp?page=library
