I'm trying to install the GitHub for Windows that I downloaded from the GitHub site. However, I get the following error message:

Application cannot be started. Contact the application vendor.

I'm curious if anyone else has ran into this issue, and knows of a fix?

Below is the info from the log file:

PLATFORM VERSION INFO Windows : 6.1.7601.65536 (Win32NT) Common Language Runtime : 4.0.30319.17929 System.Deployment.dll : 4.0.30319.17929 built by: FX45RTMREL clr.dll : 4.0.30319.17929 built by: FX45RTMREL dfdll.dll : 4.0.30319.17929 built by: FX45RTMREL dfshim.dll : 4.0.41209.0 (Main.041209-0000)

SOURCES Deployment url :

It seems like the error message itself isn't specific to Git, but more of a universal message that Windows installer throws because I noticed when doing a Google search people trying to install other applications had an identical error message.

I wasn't able to find any information on GitHub's website about this error either. :(

Thanks for any help-

It looks like maybe you need to install .NET 4.5, or possibly reinstall .NET 4.5? Are you able to run other .NET programs? – Mark Allen Oct 4 '12 at 18:21
Darn, too easy I suppose. Just even clicking your link in that log file ( was enough to launch GitHUB for me, which I already had installed. If you click that link, does it even try to do something? – Mark Allen Oct 4 '12 at 21:50
I've tried running that too, but I get the same error. I believe the error is actually "Click Once" app related, and not GitHub itself. So far, GitHub support hasn't been able to help me with this issue either. – snowBlind Oct 8 '12 at 19:34
That's actually good news - now you can try a bunch of fixes specific to that:… – Mark Allen Oct 8 '12 at 19:47
Adding the possible solution as an 'answer' just in case it helps. – Mark Allen Oct 8 '12 at 19:47

  • From the Windows Start Menu, choose "Run" (or type Windows (Windows Key)+R).
  • Enter the following, depending on your version of Windows, then click the "OK" button:

    • On Windows XP:

      %userprofile%\Local Settings\Apps 

      (which may be C:\Documents & Settings\(your username)\Local Settings\Apps)

    • On Windows VISTA / 7:




      (e.g., C:\Users\(your username)\AppData\Local\Apps)

  • Delete the 2.0 folder

Set to community wiki because I copy/pasted this from somewhere else. – Mark Allen Oct 8 '12 at 19:48
I tried this with no luck a few days ago. – snowBlind Oct 9 '12 at 15:23
Well it was worth a shot, sorry. :( I'd still pursue solving ClickOnce applications not starting in general, that does seem to be the actual problem. – Mark Allen Oct 9 '12 at 17:25
Thanks, this worked like a charm! – Mitch Labrador Jul 8 '13 at 16:48
This fixed my issue. Having a similar problem with the same message on Windows 8. – Basilio German Aug 29 '13 at 18:52
