First of all I would like clarifying for me these points:

  • Do you buy the DVD of a legitimate place and it was really genuine and not some bargain sale engraved DVD?
  • To finish the installation, did you extract the error code from the first moment that it has tried to activate or extracted it later?

Secondly, the reason of my questions is that this error code indicates that the key of product that has already interfered has been activated, not validly, it has already been used to activate the system for a maximum times limit, or cannot be used to activate the Windows Dress, therefore, you must obtain or change to a key of different product following(continuing) these steps:

  • In the field of product key, scribe the key of the product and, next, click in following (It verifies the product to insure itself of introducing the correct product key).
  • Continue(Follow) the steps of the Assistant of activation of Windows to complete the activation process.

If this method works then finish the opposite if the key of the product at present in use is genuine and valid, try to activate by phone following(continuing) these steps:

  • Click in Beginning and, next, click in team(equipment).
  • Click in properties of the system in the hardware bar and, next, click in haga click here to activate Windows now in the section of activation of Windows.
  • Click in showing other ways of activating.
  • Click in using the automated telephone system and, next, continue(follow) the instructions that are provided.


If this method does not work for you, he(she) can ask someone for help or can get in touch with the support for its next steps.
