Hidden SH3 file messing with reinstall!

[sixth_iowa@mchsi.com]

I can't install SH3 without getting the dreaded "error 1608: Unable to create driver instance- return- code 2147024894". I originally installed the game with the fronflotille mod 2.0 but decided to try the greywolves mod. I made the mistake of uninstalling and trying to reinstall when I got the error message. I have since installed both Spinter Cell/Splinter Cell: Pandora Tomorrow/IL2 Forgotten Battles, and the Ace Expansion Pack add-on all with no problems. Both those games are Ubisoft too.

The SH3 file in the program folder is gone as is any reference in the uninstall registry although it still shows up in the windows add/remove programs titled Silent Hunter III. The temp folder and anything SH3 related in the my documents is also gone. Everything on my computer is up to speed driver wise and I use windows automatic update.

I've used some free registry cleaners to no avil. For some reason my system restore won't solve the problem either. Anyone have any suggestions out there?
