Cannot write to the registry at all

Any help would be appreciated as I am totally stuck

Only have one account on Vista Home Premium, which I set up when firs
loading up the PC - this account is the admin account

I recently trialled some Adobe software, the software ran out and
attempted to uninstall. An error message came up saying I didn't hav
sufficient priveledges to write to the key/registry and I couldn'
properly uninstall. I followed some instructions and tried to make th
key available to access using permissions, this seemed to work. I
still wasn't working so I searched the net and came across Rev
Uninstaller, and managed to remove all instances of the software

I then attempted to install some different software and this faile
with a similar message - "do not have permission to access the key"..

Today I tried to load up iTunes and now I'm getting the same messag
when double-clicking the logo on desktop. So I attempted to uninstal
iTunes, then re-install. I can't uninstall as I get a key error again
and when I try to install the same error occurs

Everything points to me not being able to have full permissions t
access the registry, but I can't find out exactly how to

1. Uninstall correctl
2. Reinstall correctl

If anyone can help I would appreciate it - otherwise, I'm going to wai
until Windows 7 comes out, wipe my HD and do a fresh instal

Thanks
Ton

Check how it is in safe mode -if the same open regedit go t

HKEY_LOCALE_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CUR RENTVERSION\UNINSTAL
and check permissions to this key.Administrators group & System accoun
should have full control,Users group -rea
