registery cleaner?

Are there any easy to use or good tools that I can use to search my entire registry and delete all entries assoicated with a given search term?

For example, I have a corrupt Motorola Phone Tools. I can't reinstall it because it keeps telling me the previous version cannot be uninstalled. I can't uninstall it because the previous version is corrupt. I've tried a few different tools, Lexun, CCleaner, but no help (or maybe I didn't know how to use them well enough). What I'd like to do is put in a search word, "Motorola" in this case and have some tool that would go through and delete every entry it finds that is associated with Motorola and then I can start again fresh installing the software.

I had a hard drive rebuild and I have several software products in this condition. Fortunately, I have the original discs and my own user data is saved, so I don't mind if I could delete all traces and start over for a given product. But I really don't want to totally reinstall Windows (XP in this case) and start 100% over. Thanks,

If the corrupt installations were installed using the Windows Installer, you can use the Windows Installer Cleanup Utility to remove them: http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.html
