# Cognex Security Service

The In-Sight Vision Suite software and its supported adapters require you to attach the Cognex Security Dongle USB to your computer to ensure it is properly authorized for use. Attach the Cognex Security Dongle to your computer via a USB port before you launch the adapter.

In addition, the Cognex Security Service 3 process is required to verify the presence of the USB security key and the licenses for the vision tools that you want to use. This process is installed along with In-Sight Vision Suite, and is executed once the installation of In-Sight Vision Suite is complete.

Note:

- The software requires that a valid Cognex Security Dongle is installed during all phases of operation. Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.
- The CodeMeter™ Control Center application for the Cognex Security Dongle can detect multiple dongles connected to the same computer. However, when using multiple dongles, you can only use the Cognex software and features whose licenses are present on the first dongle listed in the CodeMeter™ Control Center application.

- If you have In-Sight ViDi 1.2.0 (or a newer version of the adapter) installed with VisionPro 9.6 on the same PC, then uninstalling either of these software renders the other one unusable, as their shared Cognex Security Service is also removed during uninstall. To fix this problem, uninstall both applications, and then reinstall the one that you wish to keep using.

  When using multiple versions of In-Sight ViDi on the same PC (such as 1.2.0 and 1.3.0), this behavior affects VisionPro 9.6 only if both versions of In-Sight ViDi are uninstalled.
