When I try to start it. The loading screen flash by in 1 millisecond then dissapear. Iv'e tried the devenv.exe /Setup solution, but devenv.exe won't start either.
Don't know what to do! I think it has something with to do with devenv.exe. Because after I used the selector, it has been corrupt.
Assuming you've already tried the basics (turning it off and turning it back on again, etc.), you may want to try running it as administrator. Right-click>Run As Administrator
I've had some issues on and off with VS not always working for me unless I run as admin.
If that fails, you can repair the installation by going through the Programs and Features menu.
