Hi guys, how do i uninstal 737NGX of my old computer, to install it in my new computer. so activaction works and all of that?

I think you just uninstall via the Windows control panel (add/remove programs).

the question is will the key accept another activation... i tried for instance to activate on a second pc and won't activate!

well i think this matter is sensitive ? i send multiple questions about this but no answers from pmdg? hello ..... are you there..... it must be possible tp install this expensive product on a second pc/laptop or not????
