Install any program and then run the wine uninstaller. The program should be displayed (which means it has an entry in the registry uninstall keys. Then select the program and select remove option. The program should then be removed from the uninstaller list (meaning its entry has been removed from the registry).
That's what I did. Apparently it works for some installers but not for others, so please specify an installer that fails for you.
