I have a Dell 8300 desktop running with Windows XP Home edition with Service Pack 3. I recently bought a new retail box which came with Genuine Windows XP Professional Upgrade. I can read written outside the box that it can upgraded from XP Home to XP Professional. Well i would like to do that but want to keep my existing files and programs untouched. Now the problem i am facing is whenever i start the process i use to get an error message on my screen saying "The software installed in computer is newer than the one on the CD" and installation quits itself.
I get one more message after that which says to restart the system and use the CD to perform the new installation but it was not my intention. I tried to get MS Support but the support dialog box says it cannot recognize the product key. I have no idea what else to do. Can anyone please help.
Thank you.
