Unable to install windows XP SP2

[Guest]

I have tried all the things posted on net about the this problem and still
not able to upgrade to SP2.

I have checked all the permissions and they are full rights. I m logged in
as Administrator and still not able to find where this access is being denied.

Following is the error message from the \windows\svcpack.log
