AD Connect Sync License key showing as DEMO

Problem: AD Connect Sync shows license key status as 'DEMO' even after activation of a valid license key.

Reason: AD Sync utility loads information from System Registry and HC AD Sync installation directory, so if one has connected the machine with a user who has insufficient system level privileges then such issue might appear.

Resolution: Either access the machine Administrator account OR open the ADSync tool by run as administrator.
