Compilation failed because the compiler couldn't be executed! ?

So...i have this error:

Could not start compilationWin32Exception: ApplicationName='"C:/some ol' bullshit/Unity/Editor/Data/Mono\bin\mono.exe"', CommandLine='"C:/some ol' bullshit/Unity/Editor/Data/Mono\lib/mono/unity\us.exe" @Temp/UnityTempFile-8b6d38ce953ed214eb25be1907023d9a', CurrentDirectory='C:/some ol' bullshit/Unity/PWAPG2/Assets/..'

And this warning after it:

Compilation failed because the compiler couldn't be executed!

I tried restarting,uninstalling,installing but nothing. My old project work but if i want to make a new one it won't work. I've noticed that if i delete the standard assets folder the error disappeares but if i import it again(the character controller package) the error comes back.

Any solutions please? I would appreciate a solution that doesn't involve installing windows again.
