With this tool you can activate your floating license key. You can install this tool on a server where then the clients will connect to.
If you purchased an upgrade floating license and which to use it on a new system, then it is necessary to deactivate the previous floating license from the old system. When you installed the new version of the Workgroup Manager on the new system, then you can activate the old license and the upgrade license together.
Make sure that you create an Enfocus ID first as you will need to use that account to activate the key.
