Service Pack 2 Set up error

[gus burbee]

I have had a difficult time with this installation I keep getting a set up
error when I install xp service pack 2.
The error reads: Service Pack 2 could not back up registry value.
HKLM\SYSTEM\CurrentControlSet\Services\Eventlog\Security\Security,\'Eventmes
sagefile\'. 5: Access is denied


Any help would be Great!

Thanks,

Gus
