Answer 1

After contacting support, they emailed me and helped me work through the problem preventing GitHub for windows from installing.

This is a problem with the ClickOnce Application Cache.

1. Before proceeding make sure that you have connectivity.
2. Sometimes Firewall may be blocking this *.application
3. So turn off you firewall for private and public profile and then retry.
4. If the issue persists, you can use the process specified below.

1. Hold down the Windows key and type R.
2. Type in rundll32 %SystemRoot%\system32\dfshim.dll CleanOnlineAppCache in the run dialog and hit Enter.

Then try installing the application.

If that doesn't work, there's a more manual approach to ensuring the cache is cleared - you can delete the ClickOnce Application folder directly. On Windows Vista or higher, this will be the %LocalAppData%\Apps\2.0 directory. Simply delete the %LocalAppData%\Apps\2.0 directory and restart github for windows.

If nothing seems to happen after running the installer, you may need to restart Windows, or explorer.exe (if using the .msi installer, the app may be in: %LocalAppData%\GitHubDesktop)
