When ever i try re-download GF It goes up to Launcher.exe then it says "Run time Error!" If i push "Okay" on that, then it makes me close the launcher.

Is there anything blocking processes like a security software?
Did you try right clicking the installer and selecting run as admin?

Hey, a runtime error on the launcher indicates that you don't have the microsoft vistual runtime distributable package installed This can be resolved by downloading and installing this package from microsoft. Please try this, then try running the launcher again. If you still have issues, please reply here and I'll do my best to help you.
