Issues with licensing can prevent the operation of Motive. This list identifies possible causes for various licensing errors that can occur, and how to resolve them.
The Motive license folder is located at C:\ProgramData\OptiTrack\License. You can also open the License folder using the link on the Motive splash screen.
There are several potential causes when the License not found message appears.
Check the license folder. The license file name contains the 6-digit serial number of the USB key associated with it. Confirm the number matches the serial number on the USB key. If the key and the license are mismatched, contact support.
Maintenance Licenses extend the term of the license purchased with the OptiTrack system, which is referred to as the Initial License. For a maintenance license to work, both it and the initial license must be in the Motive license folder.
Check the license folder. The name of the license file will indicate whether the license is an initial or maintenance license.
If the Initial License is missing, use the License Activation Tool to download it again. You will need the licensing information provided on the License card when the system was purchased to do so. This will download the initial license and all associated maintenance licenses.
