After following the excellent directions for the uninstall and reinstall and checking to make sure there are no hidden FSX "nuggets" anywhere and also following the instructions setting up a new path for the installation (C:\FSX) I go to reinstall. I receive a message saying there is already a copy of FSX on the system and continues to load to the default location. Can anyone point in the right direction and what I may doing wrong? Thanks.

All right it seems I now have a more complexing issue. I continued with the reinstall even after the message said I needed to uninstall the program. I loaded FSX and when I attempted to load the acceleration portion it said the program wasn't in english and would not allow the reinstall. So here I am without FSX at the present moment and without a clue on why the Win 7 will not completly uninstall the program. I could use a little help here. Thanks.

Check add/remove programs to see if it uninstalled all of fsx or just acceleration. If it won't uninstall, manually delete all the files/folders, be sure to check in appdata/roaming as well.Download & run ccleaner registry scan (it's free). Make a backup the first time it asks you to, then run it 2-3 more times or until it gives 0 registry errors. Reboot the pc & you should be good to go for a fresh install.
