After a proposed update, my license is not more accepted


TeamViewer 12 asked me to update, and after this update, my license was not more recognized.

I have a premium license with 2 connections in our 3-people company, but it had changed it to a free license. Even my account is not recognized anymore on this PC. On another PC (my netbook) where I have refused to make this upgrade, both my license and my account are working as before.

When I try to put my license number I have from TeamViewer 11 (I have not received a new license number, my serials were upgraded automatically), TeamViewer says it is not valid for this version.... very strange....

The upgraded (non working) version is 12.0.83369.

What can I do?

Thank you for any hint!

  • I got the samne problem, my license is not working anymore after the release of the final version 13. It was recognized initially but after 2-3 weeks it switch to trial version. How can I fix this?  This license that we have is for Corporate use for 18 connections.
