After an upgrade from Windows 7 or Windows 8 to Windows 10 or after a regular Windows 10 update has been installed, the eLicenser Control Center displays the Soft-eLicenser as 'deactivated'. Applications which need to have a valid license cannot be started anymore. Performing a 'Maintenance' does not work to recover the Soft-eLicenser.
Please uninstall the eLicenser Control Center using the Windows routines (Control Panel > Programs and Features) and reinstall it using the latest available version you can download from here.
Alternatively, you can also start the existing eLicenser Control Center installation as an administrator by right-clicking the 'eLCC.exe' file in 'C:\Program Files (x86)\eLicenser\eLCC' and choosing 'Run as administrator' from the contextual menu. Afterwards, running the 'Maintenance' in the eLicenser Control Center fixes the deactivated Soft-eLicenser.
