You can return a borrowed license back to the Tekla license server before the expiration date.
A borrowed license is automatically available on the license server on the day following the expiration date.
However, the Borrowed Licenses area in Tekla License Borrow Tool is not automatically updated. The license should be returned to the server that has the same name as the name of the server from which the license was borrowed. We recommend that you always return the expired licenses when you want to stop borrowing a license.
To return a borrowed Tekla license:
Ensure that you are connected to the license server.
Close Tekla Structures.
Go to Tekla License Borrow > Tekla License Borrow Tool through the Start menu or Start screen , depending on your Windows operating system.
Select the Return check box in the Borrowed Licenses area to select the license for returning.
Click the Return button to return the license.
After successful returning of licenses, the Borrowed Licenses area is updated.
