Steve I install FSX-se on a computer that has not had fsx-ms on it. But I have used the Migration tool for P3d on it. I no longer use the tool, cleaned the reg according to your instructions and removed any fake fsx-ms files. Installed FSXSE it install as FSX for all files and folders as far as I can tell. All addons have no problem installing.
But IF looks for the Fsx-se config file.I updated to the new version. What can I do to get IF to work? Should it be looking for fsx config files?
