Hello,
Today i installed a game that runs .NET Framework 3.5.
So, after installing the game it opened me the .NET installer and after that it said [Restart now] [Restart later] i clicked on [Restart now].
After restarting the computer, it asked to install again.
i went to Windows + R: appwiz.cpl and it were disabled, i tried to install from the website, still the same.
Installing from the cmd line it said the error 50
