Greetings mah fellows, homies, pals, buddies, an' friends!

Seeing this page means you most likely have experienced the greatness that is uninstalling the Visual Studio Authoring Extensions through the Control Panel.  The greatness being great pain in the membrane!

So now what?  Whatchu gonna do bro!  Wutchu gonna DO BRO!

Now now, the last SCSM TechNet Guru, shall show you, the pupils how to spin the wheel of fate and win!  Spin and Win!

Aite, let's talk geek speak:
You need something called MicrosoftProgram_Install_and_Uninstall.meta.diagcab

This thing is gonna take in a GUID of the installed add-on we can't seem to get rid of cause it wants the MSI to uninstall.

Now, how do we know this GUID?

Well, Windows stores the list of GUIDs where you can find it in the registry.

Open regedit.exe and navigate to:  HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Now you'll see a bunch of keys which are the GUIDs underneath.

You can go "Ctrl+F" and search for Visual Studio Authoring Extensions

You should now know the correct GUID you need.

Alright, copy that down cause we need it later.

You will now run the MicrosoftProgram_Install_and_Uninstall.meta.diagcab

  1. Enter your admin creds if prompted
  2. Click Next
  3. Click Uninstalling
  4. Wait around like a boss
  5. Click "Not Listed" then hit Next
  6. PASTE IN YOUR GUID NOW then click Next!
Now you have done it, you managed to get something uninstalled that should've been easy in the first place, but it wasn't.... but you can be the first place instead, cause you a winner, a real winner bro!  That's right, A Winner is You!

Note:  If you plan to install a newer version, you may encounter an error stating "The specified account already exists"
My solution was to manually:

Delete folders if exist:
  • C:\Program Files\System Center 2012 Visual Studio Authoring Extensions\
  • C:\Program Files\System Center Visual Studio Authoring Extensions\
  • C:\Program Files (x86)\System Center 2012 Visual Studio Authoring Extensions\
  • C:\Program Files (x86)\System Center Visual Studio Authoring Extensions\

Uninstalled the SCSM web extensions and then enter regedit.exe as admin:
  • Deleted Key - HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VSAC

Navigated to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders and searched for "Visual Studio Authoring Extensions"
  • Deleted all string values that were Visual Studio Authoring Extensions
Was then able to successfully install newer version.
