Problem installing Service Pack 2

[Guest]

Service Pack 2 will start to install and then when it says updating registry
keys, it gives me a ACCESS IS DENIED error and then it stops the install and
uninstalls everything. How do I fix this problem?

You must be logged in as the Administrator to install SP2.

I am logged in as Administrator. Any other ideas?
