# Cognex Security Service

In-Sightrequires that you attach the USB Cognex Security Dongle to your computer to ensure the software is properly authorized for use. Attach the Cognex Security Dongle to your computer via a USB port before you launch a In-Sight application.

In addition, the Cognex Security Service 3 is required to verify the presence of the USB security key and the licenses for the vision tools that you want to use.

CAUTION: The In-Sight Vision Suite and In-Sight software require that a valid Cognex Security Dongle be installed directly to PCs running the software during all phases of operation (programming, processing, training, testing, etc.). 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.
Note:

If you have In-Sight 1.2.0 (or a newer version of the adapter) installed with VisionPro 9.6 on the same PC, then uninstalling either of these software will render the other one unusable, as their shared Cognex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 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 are uninstalled.
