Uninstalling the license server
In Control Panel, browse to the list of installed applications, select CADMATIC License Server 2.0, and then click either Modify or Uninstall to uninstall the license server. You are prompted whether to allow the license server folder to be removed.
If you have previously used the license server with an USB key, you can uninstall also the related Sentinel System Drivers from this view, since USB key is no longer used by license server. You must restart the computer after this.
