The license file, extendsim.lic, on the License Server needs to be updated and reactivated whenever there is this type of change to the license.
To change the number of concurrent users on your Floating license, first contact Imagine That Inc. or your ExtendSim Distributor.
Then, you will need to reactivate the License Manager on your server updating the license file, extendsim.lic.
Existing Client devices will automatically be updated once the License Manager on the Server has been updated.
For complete details, see the document titled Reactivating • Floating Licenses.
