How to Uninstall WSUS 3.0 after you have (removed/fucked up) the database manually

Well if somehow your wsus 3.0 database becomes corrupt.
Due to an Database administrator removing the instance for example.

I tried to remove through the Add/Remove programs dialog but all I got back was.

And voila the program was removed from the ADD/Remove Programs dialog.
So I had nothing.

Inspecting the Wsus installation log at %temp%\wsus*.log
Reveals the following:

MSI (s) (8C:74) [11:17:38:402]: Product: Microsoft Windows Server Update Services 3.0 — Removal failed.

There you have it, you have absolutely nothing to work on.

Then you will have to do the following to get your WSUS back.

First what I did was to completely remove the Database.
I had used the internal WSUS 3.0 database so to remove that I did the following.
Go to command prompt and there type in:

msiexec /x {CEB5780F-1A70-44A9-850F-DE6C4F6AA8FB} callerid=ocsetup.exe
I found this on the Microsoft Technet

Microsoft Technet

This starts the deinstallation of the Windows Internal Database.
So the first hurdle has been taken, the database is gone.

Now I wanted to start the installation of wsus again but this resulted in the same vague error messages I already stated above.

Now I had to remove the complete installation of WSUS 3.0 which is an msi app.
I remembered that there was an Windows Installer CleanUp Utility.

I downloaded it from Microsoft:
Windows Installer CleanUp Utility

When I ran that utility on the machine it showed me alot of programs but also the crooked WSUS 3.0 I selected that one, and choose [Remove]
In the application log showed the following:

0020: 32 44 44 35 32 7d 2DD52}

That is what I wanted to see.

After that I manually removed the installation folder of wsus which was in my case
D:\WSUS.

This enabled me to re-install wsus 3.0 and its now purring like a kitten.

Here is my clientdiag on the commandprompt on my machine.

C:\clientupdate>clientdiag

Yes I have re-downloaded all the updates, maybe its possible to leave the download folder for the updates but I havent tried it.

I hope this will help you in uninstalling wsus and reinstall wsus 3.0.
