I had a similar problem a couple of years ago on WinNT 4.0 /
Oracle 8.0.5. Customer disalowed reinstall of windows, so we
cleaned the machine of all Oracle related stuff (many times
over!), reinstalled. Then Oradim80 would fail to create a
new instance. I worked with Oracle Denmark on it for quite
while. Finally in a day long session we found one of those
registry legacy keys, that you cant normally delete, that
was actually deletable. Deleted it and everything worked
fine!
Try deleting everyone of those keys related to Oracle!
Anyway here is a metalink article on the subject. Good luck!

PURPOSE
This article describes the procedure how to manually perform
the actions to
create a "clean machine" on Microsoft Windows 95/98/NT/2000
and how to
manually remove all Oracle components (e.g.: oracle RDBMS
database server,
IAS, OEM, client installations, etc) and services from your
computer.
SCOPE & APPLICATION

Note the value of the key INST_LOC, this is the location of the Oracle Universal
Installer. The default location is C:\Program Files\Oracle\Inventory. If this
value is different, make note of it, so we can delete these files later.
