Unity Editor has stopped working error

Unity Engine
1

Hello,

I just bought a new notebook. Installed win8.1 pro, then I tried to install Unity but I got this visual studio error.
“Microsoft Visual Studio Community 2015 installer is blocked with error -2147205120”

I updated W8.1 with KB 2919355. Then I reinstalled and it worked. I had no error during installation. But after that I couldn’t run Unity. I’m receiving “Unity Editor has stopped working” error.

I searched for possible solutions. People said that it might be related to dual GPU. First I forced Unity to run on Nvdia GPU. Didn’t work.
I followed nessim’s steps in this thread.

I tried forcing to use 3d11 and opengl. They didn’t work neither.

I changed compatibility also didn’t work.
