I\'m trying to install github for windows when I received this error:
Application cannot be started. Contact the application vendor.
The error
I had this issue as well installing github on Windows 8 x64, I tried all suggestions above related to removing the 2.0 directory but with no luck. Later I found a blog saying that one guy solved this issue by downloading the installer using Internet Explorer (weird right?) Surprisingly for me, it worked! Hre is the link https://github-windows.s3.amazonaws.com/GitHub.application So I recommend you to do the same, at least IE is worth for something :)
