Hi... :( I hope that someone can help me. I have had and flown the PMDG747 (FS9) a number of times.. now, suddenly the Load Manager says that it can't find the MSFS installation. It would let me fly the program, but I keep getting insufficient fuel message. I tried to repair through the Disk, and no luck.. I then uninstalled the B747 and now it won't let me reinstall it b/c it says that MSFS isn't installed. Yet, it is installed. Any idea? If you are saying to reinstall MSFS, I am worried that I might not be able to reinstall the 737 as I downloaded that version from PMDG and don't have the disk.Thanks in advance.Bob LeBoeuf

Something has messed with your registry. Look at the pinned topic for FS9 installations not found. Hope it helps.

Thanks Dan... But although I've had a computer for years, I've never messed with registry. Can you tell me exactly how I should do it? And, what to do?Bob

I am a bit confused... should I just run "http://tweakfs.com/download/fs9path_utility.zip" and then you think that might clear up the problem so that I can reinstall the 747? And, are there any tricks or questions that I'll need to answer....As I said, I am not too experienced with this stuff..Tks againBob LeBoeuf

Wow... I ran the utility and it seemed to work. I was a bit afraid of it (as you can see from my earlier posts, but I did a system restore point before it. Sure enough, the path didn't exist, but it took a little clicking around within the utility, but it seemed to find it OK... Also, I do remembering uninstalling FSX and then reinstalling it... perhaps that is what corrupted the registry....Thanks again... hope it works on from here.Bob
