Your problem doesn't obviously have anything to do with GSX, or the Live Update. From your report, it seems you still have registry keys for FSX, which you shouldn't if you don't have FSX installed.
Some of the most common reasons why you still have FSX registry keys when you don't have FSX anymore are:
- You removed FSX manually instead of uninstalling it
- You installed FSX, then you installed FSX:SE, then you removed FSX without reinstalling FSX:SE.
- You used the dangerous P3D Migration tool, which has created fake FSX registry keys to force the installation of products that are not compatible with P3D. Our products ARE compatible with P3D and FSX in the proper way so, using that tool would of course confuse them, as will confuse any other "proper" product that supports both FSX and P3D as separate products, instead of using that hack to force-install FSX products in FSX.
So, you don't really have FSX installed, you should:
- Clear all your FSX registry entries, which you shouldn't have if you ran the FSX uninstallers.
- Uninstall the Migration tool if you ever used it, assuming it has an option to undo all the damage it did.
