I don't know what happened to my system but FSX suddenly stopped working. Nothing I tried seemed to help. I instituted a restore to a previous system installation. It didn't fix the problem. The restore point was back to a point where I had uninstalled the PMDG B738-9 - except there was still an entry in the Windows 7 "Programs and Features" list. I tried to uninstall the program from there but I received and error that indicated that setup.exe had failed. I also tried to re-install the aircraft and a message displayed indicating that I had a previous installation of the program so the install program terminated.
At present, I have no PMDG folders in my SimObjects/Airplane or FSX main folders, I can't uninstall the aircraft and I can't re-install it.
I thought perhaps I could manually edit my Windows registry to fix the problem. I removed one folder index and that didn't fix the problem. There were no other registry entries associated with PMDG.
Can someone please help? I'd like to get back to flying.
