I found this link https://store.steampowered.com/app/3141 ... m_Edition/
not a bad deal for only $ 25.00
trust me this is the way to go you get a bug free FSX without having to go through registering it no keys no license and no Discs
And if you should have to reinstall all you have to do is log on to steam and redownload it. It does not get any easier than that
the best feature is if FSX does have issues all you have to do is to verify your files if problems are found they will be fixed
I was one of the original Beta testers and FX steam is the best thing that ever happened.
