  • Hello Roy Mathew,

      I am sorry, that error message is not very good.  Basically it's Vista's way of saying you need to use the Activate by Phone method instead of Activating over the Internet.

     If you are unsure or unable to get to the Activate by Phone dialog, the short cut is to click the Start button and type slui 4 in the search field and then press the "Enter" key. This will bring up the Activate by Phone dialog window. Follow the steps provided by the window. The phone activation process should only take about 6 minutes.


    Thank you,
