Hi
After installation of Uniface CE (includes patch 044) your license activation window disappear and you see below logs:
ERROR: The License Activation Utility failed, could not obtain a license. Fatal error: 8011 - License not available.
or
Sentinel errorcode is 210018
P.S You can use "/who" command to check your patch level.
