I've recently reinstalled Windows to upgrade to 64Bit version of Windows 7 to use all of my Ram, but since then I'm unable to start Arma 3.
I've also reinstalled Arma 3 with all the drivers provided by Steam and additionally all vcredist versions from 2005-2015, .NET Framework and directX.
To fix the problem I tried reinstalling the game & drivers, run sfc /scannow to check for any missing system files and run a Steam-check for any corrupt game files.
I have no idea how to fix the problem because all advice on the internet say to reinstall windows which I think wouldn't help or to install drivers which I should all have.
I would be happy if someone could help me fix my problem.
Sincerely,
Markus Hoffmann
