See this MS Knowledge Base article:

You receive an "Access is denied" error message when you try to install Windows XP Service Pack 2
http://support.microsoft.com/kb/873148

Note that editing the registry is involved.

Yes my account has administrator and this is the message i get:

1513.703: DoRegistryUpdates:SetupInstallFromInfSection Failed for ProductInstall.GlobalRegistryChanges.Install error: 0x5
1513.703: INF_REGISTRY Failed
1513.703: DoInstallation:DoRegistryUpdates failed
1526.406: Unregistration of sprecovr successful
1526.812: Access is denied.
1531.359: Message displayed to the user: Access is denied.

What do I do?

Thanks,

Mike

I can't tell you any clearer than the steps outlined in the article Mike.

Print them out and follow them through carefully. Get someone to help you if need be.

It's not an easy thing to explain in a few words to a person not familiar with the registry, etc. There are some things I could suggest that may help you avoid getting the 'No Installation' message in the first place and I think that's a better way for you to approach this.

First off I will assume you are using the Home version of XP and not XP Pro. Correct ?

Download, install, and run this tool.

Do the same with this program. Only difference: update it after it is installed, before you run it.

With these and especially with the SP2, first disable your AV program. It can interfere with the install. Post back after you get this much done. Don't fear asking questions.
