EthoVision XT (version unspecified) displayed an “Insufficient License (Id 10073)” error when he attempted to open a previously saved experiment. The license number was correct and asked whether a setting in the experiment needed to be disabled. The FAQ below offers general guidance for resolving insufficient‑license errors in EthoVision.

FAQ & Step‑by‑Step Instructions

Q: What causes the “Insufficient License (Id 10073)” error?
A: This message appears when an experiment uses modules or features that are not included in your license, or when the license key (dongle or network seat) is not detected. It may also arise if the license has been entered incorrectly or the maximum number of licensed users has been exceeded.

Q: How do I verify that my license is detected?
A:

• Check the license key – Ensure the USB license dongle is firmly connected to the computer. If you use a software or network license, make sure your system can reach the license server.
• View license details – In EthoVision, go to Help > License Information (or open the Noldus License Manager) to see whether your license is recognised and which modules are enabled.
• Test on another PC – Plug the same dongle into another computer running EthoVision; if the license is recognised there, the issue may lie with the original PC’s USB port or drivers.

Q: How can I open my experiment if it uses an unlicensed module?
A:

• Open on a licensed system – If possible, open the experiment on a computer with a full license. Go to the experiment’s Detection Settings or Analysis Options and disable modules not covered by your license (e.g., Social Interaction, Deep Learning, 3‑point tracking, etc.). Save and close the experiment. You should then be able to open it with a more limited license.
• Review module usage – Experiments created with specialized modules may require them for subsequent editing. Consult your license documentation or Noldus support to identify which modules are needed.

Q: What if the license is correct but the error persists?
A: Try these steps:

• Update your license drivers – Install the latest HASP (Sentinel) drivers from Noldus to ensure the dongle is detected correctly.
• Restart the license server – For network licenses, restart the license service or check whether all seats are in use. Release unused sessions if necessary.
• Re‑enter the license key – In the Noldus License Manager, remove the existing license number and re‑enter it carefully. A typographical error can cause an insufficient‑license warning.
• Upgrade your license – If your experiment requires modules that your current license does not include, contact Noldus to purchase or activate the necessary modules.

Q: Are there any experiment settings that trigger this error?
A: Yes. Enabling advanced modules such as Social Interaction, Three‑point tracking,

Deep Learning, or Physiology integration without having the corresponding license will cause an insufficient‑license error. Disabling these modules or obtaining the appropriate license will resolve the problem.
