Product key cannot be validated RRS feed

  • Question

  • Our laptop (Acer aspire 5536) came with windows vista pre installed and a windows 7 update disc.  The hard drive began to fail so backed up our files and changed the hard drive!! We have tried to install windows vista home premium from disc and tried to input the activation code on the base of the laptop. Install Windows is telling us "product key cannot be validated".  We have the windows 7 upgrade kit and product key and are unsure as to what to do now.

  • I am suspecting that your Vista retail disk install won't accept the product key from the computer's COA sticker. If you use the Product Key from sticker on the retail package then you are tying the key to the win 7 upgrade later. 

    If you have an Acer factory rebuild disk you should use that to reinstall Vista.  If not then you should contact Acer for a set of replacement disks (for a nominal charge if still available.)  If the old drive is still working and you can boot the computer with it you may be able to place it back in the computer and create the rebuild DVDs using the program that Acer has on the drive.

  • One thing you can try is to do a Keyless install (install Windows, but don't enter the product key).  During a Keyless Install, windows will automatically uses it's own Keyless Install Key which acts like a trial key. 

    Once you are done with the install, you can click the Start button, right-click Computer and select Properties.  This will take you to the System windows, at this point, you can click the Change Product Key and see if Windows will now accept the Acer Windows Product Key.

     

    If that doesn't work, then you will need to follow LVTravel's advice and use the Acer factory rebuild disk (or contact Acer for a replacement disk).

  • Hello Jurassic Steve,

     

      When you say you have tried to install windows vista home premium from disc, are you talking about a Retail Windows Vista disk or the Windows Recovery Software that came with the PC?

     

    Thank you,
