Uninstall OpenOffice

Sadly, I have to start with my experience of uninstalling OpenOffice on my XP machine. It took me a while to uninstall it because I removed the location of the original installer. I didn't know that would cause such a pain. But here is what I found.

1. Using regedit and go to:

HKEY_CURRENT_USER-Software-Microsoft-Installer-Products

or

HKEY_LOCAL_MACHINE-Classes-Installer-Products

3. Scroll down on the list there and look for the one that has OpenOffice in the ProductName field.
4. Remove that folder under the Products tree. It should be bunch of numbers.

That's it. It worked for me. I was able to install the newer version of OpenOffice.

If you can't find them there, download regmon from MS and run the installer, it will tell you the location of that registry. You might want to filter for what you need to find when running regmon.

Oh.. remember to backup your registry just in case.
