Windowsserverdocs: Cannot Remove Admin Center

[jlivingston91]

I tried to simply remove the installation (Windows Server 2019) and I am now receiving this during the removal process.

   Product: Windows Admin Center -- 1: Unhandled Exception: System.NullReferenceException Object reference not set to an 
   instance of an object.

Do we have all of the locations that I can clean out manually? I have tried the ones mentioned here with no luck.

1. Registry under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
2. Removing the folder under C:\Windows\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft
3. Removing the folder under C:\Program Files the Admin Center folder
4. Removing the folder under C:\Program Data the Admin Center folder

I had the same thing. After manually removing the self signed Windows Admin Center certificates, i could uninstall Windows Admin Center.

I fixed by deleting the self signed certificate:

certutil -store my

Find the self signed certificate from "Issuer: CN=Windows Admin Center Encryption", take note of the Serial Number (or Cert Hash or anything really that identified the cetifcate), i.e. XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

certutil -delstore my XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

This is still the same issue with Windows Admin Center (version 1904.1) !!!! WSUS reports this error as 0x80070643: Windows Admin Center 1904.1

This also happened to me when trying to upgrade to Admin Center 2007 when having 1904.1 installed,
Even if I deleted the self signed cert it didn't update, until I uninstalled the old and then install the new one.
Hope that helps

I suppose the moral here is that a non-functioning Windows Admin Center is unlikely to be removed successfully, so you need to restore it to a working state before removal.

Use Free iOBIT Uninstaller to uninstall Admin Center, it work for me.
