I just removed several viruses from my customers computer (Windows XP SP3). I am now trying to uninstall AVG 9 so we can install AVG 2011. During the uninstall process, it fails stating it does not have access to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows.
When navigating to the key manually, I get the following error. Cannot open Windows: error while opening key)
I have tried changing the permissions and owner but get the following error. Unable to set new owner on Windows. Access is denied.
Any ideas how i can fix this?
