Upgrading from Windows XP Home edition to XP Professional with Service Pack 2 already installed
Posted on 2004-09-09
I have a laptop with Windows XP Home edition installed. I decided to upgrade to Windows XP Professional, but when I insert the disk, I get the following error:
"Setup cannot continue because the version of Windows on your computer is newer than the version on the CD.
Warning: If you decide to delete the newer version of Windows that is currently installed on your computer, the files and settings cannot be recovered."
My suspicion is that since I have already installed Service Pack 2, while my CD is Windows XP Professional Version 2002 (which does includes Service Pack 1), the installer will not upgrade.
Does anyone know a way of upgrading to XP Professional without losing any of my settings, programs and data?
