Incase it's handy, since it was for me, instead of all this registry editing, there is a free tool made by Flight 1 that is called "FS_Registry_Repair", and does all this stuff for you. I just went through this whole search thing, and found that it may be a registry problem. Then I used this tool, and voila! It corrected the registry path with a simple file navigation. It asks you to navigate to your FSX.exe, (whichever you want it to be, FSX or FSX:SE) and there you go. Hope that helps!
