I think it's probably the other way around. his current install is upgraded
to SP1, but the Ultimate disk he bought is not SP1. When trying to upgrade
Vista will tell you you can not upgrade because the version you are trying
to upgrade to is older (pre sp1) than the version you currently have (sp1).
go into control panel, "programs and features", click, "show upgrades",
uninstall SP1, reboot and then try your upgrade
