Microsoft has been experiencing problems with product activation for some time, and the following message appears during telephone activation:
Fortunately, there is still the Self Service, where you can activate via the website and we will provide you with the instructions. If activation over the Internet fails, then go back and choose telephone activation. The following window appears:
Don't be irritated by the message and just look at the installation ID in point 2. There you will find several blocks with 6 or 7 digits. So just count through how many digits a block has and then click on the field for 6 or 7 digits in Self Service.
Now a new window opens and you enter your installation ID there. Then just click on the small arrow on the right and the activation begins.
You will then be asked for the number of devices. There you enter the number "1".
You will then receive the confirmation ID, which you enter in the telephone activation window of your software.
If, contrary to expectations, problems should occur, please contact us at +49 5064 6924942.
