how to delete a registry entry that won't

Damn,

Try running Ad-ware or Spybot S&D to see if there is a small app reloading them on boot. You may also want to do a search using the software name to see if the program hid an app on you. This kind of thing happened to a person I use to know and it took him several days to find all the places where there were hidden files..

:D

I found this document on uninstalling Houdini Server. Hope it helps.
