I have already gone through this painfull experience, as I always had problems installing an Oracle on a server where an uninstall had just taken place. Obviously the Oracle uninstaller doesn't uninstall perfectly.

You have to open the registry and delete each and every of the "surviving" keys manually. There are some keys in the CurrentControlSet section, having the string "LEGACY" in it. These keys have security on them. You will first have to make them deleteable. The REGEDIT tool can't be used for this. You have to use REGEDT32 for this. It's user interface for managing a key's security is similar to the usual Explorer's security dialog.

If there are services left in the system after an uninstall, you can use SRVINSTW for also removing those services. This tool is part of the NT Ressource Kit, and I think it can also be downloaded for free from the MS web site.
