The following has happened recently on my brother's Dell:
1) He uninstalled RealPlayer. When trying to reinstall, it told him his
admin-level ID did not have admin access to the Windows registry. I started
the PC in Safe Mode, went into the "Administrator" ID, and created a new
admin-level ID for myself. When I tried to install RealPlayer, I got the same
error.
2) To provide another music option in the meantime, I tried installing
Musicmatch. The installer was unable to "self-register" four items (three
DLLs & one OCX file); for two DLLs, the reason given was "access is denied".
Even though a "successful" install was reported, Musicmatch fails with an
error that appears related.
3) Media Player was then unable to burn Napster files purchased, because of
Media Player limitations (IMAPI). I tried to use Roxio Easy Creator 5, but it
failed with a fatal error. I then tried to uninstall EC5, but ran into
registry entries for which the admin-level IDs did not have Full Control. For
the first ten or so of these, I was able to keep going to the Safe Mode Admin
ID and grant Full Control. But then one came up as UNKNOWN\CLSID\key, and for
this one the Admin ID itself could not change permissions. (There were two
registry entries with the key's character string that were unalterable, but
the Admin ID could not change either.)
Questions:
1) What registry key is being referred to when it says "UNKNOWN" in the path?
2) Probably more importantly, what does it mean when even the Safe Mode
Admin ID can't change permissions on key(s)? I hope I'm not looking at an XP
reinstall here.

Thanks,
