Hi, im trying to upgrade my vista home premium to vista ultimate. However, although the upgrade advisor sees no issues, the upgrade will not let me upgrade, i can do a complete install but will loose all my program settings etc. I get this message:

"The upgrade cannot be started. To upgrade, cancel the installation and then choose to upgrade to a version of windows that is more recent than the one you are currently running."
How can I upgrade to more recent version 1st when that is what i am trying to do.

I checked in microsoft, and they report that i need to uninstall SP1. I was able to uninstall SP2 from add/remove, but i cant find SP1.

So can anyone tell me how to find it? some of the methods in the microsoft article are to advanced for me.

hello not sure on issue your having but just curious to why you are upgrading an old operating system. windows vista has proved its self to be a liability for users since the start with reliability issues. most of these have been fixed in windows 7. (probally not that much more than the cost of upgrading to ultimate.)
