Troubleshooting: Licensing

Q : License Not Found
A: Use the license check tool to check the valid date of the license. Make sure the license can be used for the version of Motive you are trying to activate. Any licenses that were expired prior to the release date cannot be used to activate newer versions of Motive.
  • First of all, if you haven't already done so, make sure you have activated the software license. If you have successfully activated the license, there should be a license file (DAT) placed under the license folder directory C:\ProgramData\OptiTrack\License
  • Then, check to make sure the matching USB Security Key is plugged into the computer. You may want to open up the About Motive pop-up and check whether if all of the license files and the security key is being recognized by Motive.
  • If Motive still doesn't open up even with the license file and the Security Key set up properly, try deleting the existing license file and reactivating using the license information and the serial number on the Security Key.
Q : Cameras do not appear on Motive
A:Make sure Security Key is connected to the computer and try restarting Motive.
  • If the Security Key is already connected, try connecting onto a different USB port, which doesn't have much data traffic on the USB bus.
  • If it's first time using the camera system with the key, make sure the computer has access to the Internet for the camera to go through the initial registration with the security key.
Q : USB Security Key is not detected
A: Make sure the USB Security Key is properly plugged in. You may also want to try using a different USB port.
  • Make sure there is no USB Hardware key plugged along with the USB Security Key. Only one key must be connected in order for Motive to recognize.
  • Check if there are a lot of USB devices on the USB bus that may be transferring a lot of data, use a USB port on a bus that doesn't have a lot of devices connected.
