I'm trying to set up Microsoft Flight Simulator 2004 (fs9) with Windows 10 (HP computer if it matters) and having issues. It didn't give me any problem to install, but it won't run. At one point it told me something about permissions, and I've tried right clicking and running as admin but still won't open at all. Any more suggestions to try? I'm totally new to this and fairly tech illiterate, so please dumb it down for me as much as possible. It's for my 12yo son who is eager to get started. 🙂
