This article applies to all TeamViewer users getting the message "Your trial has expired".
Update from September 17th, 2020:
In case you are installing TeamViewer on or after September 17th, 2020, you are no longer able to start a trial directly during the installation. The software will offer you during the installation to contact our Sales team to request an official trial that allows you to test TeamViewer with the full feature-set of a licensed version. Learn how to install TeamViewer and request a trial here.
All other users can benefit from the default installation of the free version of TeamViewer.
The following article only applies to devices that have been downloading the TeamViewer software prior to September 17th, 2020.
When you see a dialog saying your TeamViewer trial has expired, this means that TeamViewer was installed on the device and someone chose Company/ Commercial use or Both of the above upon installation to classify the intended usage.
Alternatively, your machine runs a Windows Server operating system, classifying usage as commercial automatically.
Please contact our sales department to find out how your company can benefit from using TeamViewer!
The alert 'Your trial has expired' may show up on a device used with a commercial license, if the licensed account is not logged in. TeamViewer licenses are account-based, meaning the license is only recognized when a licensed user logs in to the device.
To sign in, click the words 'Sign in' in the upper left corner of the TeamViewer application, and enter the credentials for your licensed TeamViewer account.
You can verify licensing afterwards using the About TeamViewer window.
Should the message persist even after signing in, please contact our support team for further assistance.
If you believe that you installed TeamViewer and chose Company/ Commercial use or Both of the above accidentally, and you are using TeamViewer excusively for personal, non-commercial use, then we may be able to remove the trial period for you so that TeamViewer reverts back to the free version.
Please use this form for the TeamViewer Personal Use Verification to request this.
Note. This is the only way we can assist you with this issue!
