# Licensing

The use of some functions requires you to purchase a license. This includes industry-specific solutions and special functions, such as the integration of cash point systems or use of the h.264 de-/encoder.

### Activate licenses

After purchasing and receiving the activation IDs, enable them in MxMC as follows:

1. Open the License Management (Window > Licenses menu item) and click on Activate Licenses.
2. Enter a valid activation ID and establish the number of licenses that will be installed on this computer.
3. Click on if you want to license an additional product. Enter the corresponding activation ID in the new line and enter the number of desired licenses.
4. Click on to delete a line.
5. When you are finished entering all activation IDs, click on Activate. MxMC connects to the license server for activation. It needs to establish an Internet connection.

- Successful activation
  If the activation was successful, you will need to sign in again to apply the changes. Alternatively, you can also return to License Management .
- Activation failed (no Internet connection)
  MxMC connects to the license server for activation. It needs to establish an Internet connection. An error message appears if there is no Internet connection. It will then save an offline request file (*.lic).
  This file enables the partner/installer from whom you purchased the licenses to generate a functionality response (.bin file) on the license server. If you have received such a response, open the Activate Licenses window (Window > Licenses > Activate Licenses menu). Click on Load Functionality Response File.
  Once you have loaded the functionality response file, you will need to log back in to apply the changes. Alternatively, you can also return to License Management .

### Managing Licenses

You can view a list of all licenses that have been activated on this computer in License management. To open the License Management, click on Window > Licenses in the Menu bar.

Designation | Explanation
--- | ---
Product | Name of the licensed function.
Expiration date | This column indicates whether the license is temporary and when the licensing period may end.
Number | Number of licenses that were purchased for a product.
Device ID | Unique identifier that is determined by MxMC for the used device. Note the device ID and keep it accessible if you should run into any problems during licensing.

Synchronizing licenses with the server
When launching the program, it does not automatically compare the licenses on the computer with the license server. For this reason, you need to click on Update to reload the licenses from the server.

Updating licenses
To update temporary licenses, click on Activate Licenses. The dialog box used for updating/activating licenses is shown.

Note: You need administrator rights to synchronize and update licenses.
