I upgraded my home PC to Vista today from XP Mediacenter edition and earlier this week I had an email that the new OneCare 1.5 beta was released and “NOW WORKS WITH VISTA”. So I figured I’d install the new version of OneCare.
First, you have to uninstall OneCare before installing a new version, the problem is trying to uninstall OneCare I kept getting an error ‘0x2’. DOH!
So here’s the trick to uninstalling OneCare (courtesy of this link).
- Download the Windows Installer Cleanup Utility: msicuu2.exe
- Run this program. If it doesn’t run/install right click on it and select “Run as Administrator”. That solved this step for me.
- After installed, run this utility by going to: Start -> All Programs -> Windows Installer Cleanup.
- ‘Cleanup’ all of these apps. If you don’t see them all don’t work, I only had 3 or 4 of them:
Dr Watson for Microsoft Windows OneCare Live
Microsoft Windows OneCare Live
Microsoft Protection Service
PX Engine
Microsoft Malware Protection Engine Files
Microsoft Malware Protection On Access Scanner -
Try to uninstall onecare and if it fails then proceed to step 6.
-
Download the Windows Live OneCare uninstall program: 48034
-
Run the uninstall program you just downloaded, rightclicking and running it as admin if it fails. Now the first time I ran this my box bluescreened (yeah they still exist go figure!) but when it rebooted and I ran it again, it ran without a problem and uninstalled the app without a problem.
That’s it that’s how I managed to uninstall OneCare from within Vista RC2 (Build 5744)
