@tebeco The 2017 vsix installer has/had some issues, and in some cases ends up corrupting the extension catalog, causing these problems, unfortunately 😢

To manually remove the extension and reset the catalog so it's happy, the best thing to do is probably the following:

• Close all instances of VS
• Go to C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\ and do a search for GitHub.VisualStudio.dll. All the directories that contain a file with that name are installations of GHfVS (as VS never actually removes them, but just disables them...).
• Delete all the directories, or alternatively move them to another location (and not anything else, be careful on what you delete or move).
• Open a Visual Studio 2017 developer command line as administrator (right click on the shortcut, Run as administrator)
• run devenv /setup on that command line to refresh the VS catalog. This will take some time, wait it out.

All copies of the extension should be cleared after this, and you should be able to install the newest version without further problems.

@tebeco I mistyped the path to the visual studio installation in my initial comment, sorry! The correct path is C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions, I've updated the instructions to match

[tebeco]

i've cut/past the folder of GHfVS in a personnal folder

devenv.exe /setup took few minutes, did not open or print anything ?
I guess it's fine

I've tried to re run GitHub.VisualStudio.vsix

Still getting :

VSIX Installer
---------------------------
This extension is already installed to all applicable products.
---------------------------
OK   
---------------------------

[tebeco]

I've opened VS2017, I don't have anymore GHfVS
And I cannot install it anymore, it download it, and after I close VS, it tells me it can install on VS2017 and then while installing it crash on :

FYI :
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions
Search for GitHub.VisualStudio.dll ==> 0 Match

[shana]

@tebeco So VS 2017 runs without errors, and the extension is not listed in Extensions and Updates/Installed, correct? Can you try downloading the extension from https://ghfvs-installer.github.com/releases/2.2.0.5/GitHub.VisualStudio.vsix, and double clicking on that to install it instead of installing it through the gallery?

@AArnott Any clues as to what this error means?

[jcansdale]

@tebeco,

Could you try running the following from the command line:

set PATH=%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Enterprise\Common7\IDE;%PATH%
vsixinstaller /q /u:"c3d3dc68-c977-411f-b3e8-03b0dccf7dfc" /l:GH4VS.log
type %temp%\GH4VS.log

This should attempt to uninstall it by ID. I'd be interested to see what the log says.

yes

@jcansdale
The GUID is not the good one if i'm not wrong
also the manifest limits to [14.0) instead of [14.0, 15.0) or so ?

then i went AGAIN inside :
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions <== is this the right folder ?
Still no match for "GitHub.VisualStudio.dll"
Vs2017 does not detect installed or update anything about the extension (only online research)

And then Typing thing :

vsixinstaller /q /u:"c3d3dc68-c977-411f-b3e8-03b0dccf7dfc" /l:GH4VS.log

it output different log depending on different tries ...

• but it's either previous log (GUID not found)
• or detect the vs2015 extension only

my last try gave :

(FYI, i'll be back in 12h for testing new idea here)

@tebeco The only thing I can think of is that 2017 is not playing nice with the installation of 2015 you have in the same machine, most likely due to the VS installer bugs in the previous versions of the RC. Try uninstalling all versions from 2015 before installing the extension again, see if that fixes it.

[tebeco]

I wonder why I didn't try that ;)
I'll ping you here once I've tried (i hope tonight)

I haven't read all of this thread, but it could be that an older version of the github extension corrupted your VS installer's manifest of what you have installed. The only known workaround we have for that is to uninstall, then reinstall VS 2017. I'm not sure if you already tried that though.

[tebeco]

Github Extension was allready uninstalled from VS2015
So I took the same step as the one for VS2017
Went to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions
And found 10 matching folder that contained GitHub.VisualStudio.dll
So i've move them somewhere else

At the same time, it seems that VS2017 just detected an update so i'll keep you posted here

[tebeco]

@AArnott, no need to uninstall & reinstall VS2017
@shana thx it seems that it worked
The VSIX detected both VS2015 & VS2017 this time

The only thing that did not work is VS2017 update ;)
especial Azure stuff
Anyway thank :)
