Microsoft has been experiencing problems with product activation for several months and the following message appears during telephone activation:
Fortunately, there is still Self Service where you can perform the activation via the website and we will provide you with the instructions. If activation via the Internet fails, go back and select telephone activation. The following window appears:
Don't be confused 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 count briefly 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. Then right click only on the small arrow on the right and the activation begins. You will then receive the confirmation ID, which you enter in the telephone activation window of your software.
If, contrary to expectations, problems should arise, please contact us at +49 800 1100077.
