Installing DeviceLock Discovery licenses
To use content scanning and discovery, you need to purchase special DeviceLock Discovery licenses, corresponding to the number of computers or network resources to be scanned (hereinafter, only computers are mentioned).
DeviceLock Discovery licensing is based on the number of computers that DeviceLock Discovery will scan. One license allows you to scan one computer, regardless of whether the entire computer is scanned or a specific folder on that computer.
Depending on the total number of computers that should be scanned by DeviceLock Discovery, you must purchase the appropriate number of licenses. If multiple DeviceLock Discovery licenses are used, the number of computers to be scanned will be summed based on the number of licenses. The trial period for DeviceLock Discovery is 30 days. During the trial period, you can scan up to two computers. You can purchase and install additional DeviceLock Discovery licenses at any time.
You can install additional DeviceLock Discovery licenses by opening the Discovery Server Options node and then double-clicking the Discovery Server license(s) parameter. In the dialog box that appears, click the Load License(s) button to select the license file. It is possible to load several license files in series - one by one.
After you have loaded your license files, the dialog box displays the license information summary where Total license(s) is the total number of installed licenses while Used license(s) is the number of licenses currently in use for scanning computers or network devices with DeviceLock Discovery.
