Upgrade 8.0 to 8.0.1 windows XP

Hi, I have Domino server 8.0 installed on Windows XP.

I wish to upgrade it to 8.0.1. I have downloaded the patch from IBM - United States . However, this is not working. The patch,when executed looks for Notes program files folder and data folder. And the installation fails with the error : Installer found the incorrect version Release 8.0.

Can somebody please help?

Thanks

Subject: standard or basic?

Do you use the standard or the basic client? Note, there are different upgades for these both versions.
