This is on Windows XP Professional. This is a plain vanilla "limited 
user" created via the user accounts tool in the control panel.

Yes. That makes sense. So I checked the registry with regedit.
"HKEY_CURRENT_USER\Software\Classes" seems - for whatever reason - to be 
busted for this particular user. At least I can't open it manually with 
regedit, so my tentative guess is the same applies to the installer. 
Sorry I didn't check this first!
