Uninstall 4.5 manually on Windows?

Hello,

could somebody point me to information regarding a manual uninstallation
procedure of WebObjects 4.5 on Windows? The uninstall script crashed and
deleted itself. So I am now sitting here with a WebObjects installation I would
like to get rid of and no uninstall script to do that for me. WO 5 doesn?t
install with 4.5 still being installed and I don?t like to completely
reinstall my system.

Thanks

Regards
Daniel
