Unable to install GitHub for Windows

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 :)

Best

For Windows 8.1 64-Bit,

1. Go to file Explorer (Shortcut: windows key + E).
2. Paste this " %LocalAppData%\Apps" (without inverted commas) in you file explorer panel (which displays your current location in file explorer.
3. Press Enter key.
4. Delete the folder named 2.0 .

In my case, this worked without a glitch. I Hope this helps you

It worked fine for me. Really deleting the directory worked fine.

If you have problems locating the directory copy directly %LocalAppData%\Apps\2.0 on the explorer window. Delete every folder you find there and it will work.

Great response as it was really annoying for me.

I had this issue today on Windows 10 so the issue is still there. The solution provided by @JoeC above solved my issue. The error I received was:

I see answers here and understand that i did dumb thing. I just made small script that copied all tmp files during installation.

Made small Windows copygithub.cmd file:

:loop

xcopy  C:\Users\Stall\AppData\Local\Temp\Deployment C:\github /y /h /i /s

goto loop

Its just a copy in a loop. Start it before install github. And close after you receive an error.

Once it get a fail, all files are erased. So i didn't want to miss any file. This copy is in infinity loop. So you should stop it after you got error.

It does not solve issue, but i received working github. That's what i wanted.

The problem we had was that a third-party security application that controlled our corporate firewall on each device was blocking ClickOnce from accessing dfshim.dll over WiFi, so one potential solution for us was to have our inspectors start the .NET application while connected via ethernet and then after the app was booted up they could go out and perform their inspections.
