Create an Activation Key where you set:

•Expiry date to a date in the past, e.g. 1.1.2000

•Check Online Validation required

You create this key in the screen Administration, TAB Additional Licenses.

To apply the key, the user has to start the License Viewer. Either it is available in the program manager group (available if you use the Installation Manager) or you send him a text file with the extension.bat (e.g. viewer.bat), which has only one line with the command:

xy-player.exe -v

whereas xy-player.exe is the name of your Multimedia Player of your product. You can download a sample here.

The user can apply the key using the button Activation Key

You can check on the Activation Server, if the Activation Key was used. This is the proof, that the customer has disabled the license. Just enter the Activation Key as Entry Key and press the button Search. If the Activation Key was used, you get a list with more information like date/time etc.

Now enter as Entry Key on the Activation Server the old Serial Number. You get one or more hits, depending how often the Serial Number was used. Click on the View link.

This will open a detail record where you can lock the Serial Number.

Create a new Serial Number key so that the user can install the product on another machine.
