XP Validation failed in Parallels RRS feed

  • Question

  • Howdy. I'm really starting to lose my mind with this now (whilst simultaneously remembering why I bought my Mac in the first place! :P )

    I have installed the new Parallels 4.0 onto my iMac and then purchased a brand spanky new copy of XP Professional with SP2. Installation went fine and Windows was running happily inside it's little Virtual Machine box. That was until I tried to update it. I was directed to the Genuine Validation page and told that my copy of XP is a fake. I know this to be untrue, so I'm guessing it's some sort of compatibility issue with Windows and Parallels?

    This must have come up before (please please let it have come up before!) so any help would be muchly appreciated!

    Please tell us about the Certificate of Authenticity (COA) for your copy of Windows XP.

    1. What edition/version of Windows XP is titled?

    ·         Home

    ·         Professional

    ·         Media Center

    2. Does it read "OEM Software" or "OEM Product" in black lettering?

    3. Or, does it have the computer manufacturer's name in black lettering?                        

    4. Please provide the customer scenario you are experiencing.

    5. DO NOT post the Product Key.

    Not sure what to look for, see this page to reference your COA:


    NOTE: The data collected with the MGADT does NOT contain any information that can personally identify you. The information can be fully reviewed, by you, before being posted.

    Also Note we will do our best to support our OS, but not Parallels for MAC.

    Thank you for your participation here on the Windows Genuine Advantage (WGA) program forums. We look forward to working with you.
