License Not Found. Activate License Dialog Keeps Showing.
DETAILS
When launching Opcenter APS, the license is not being found, or it is being detected, but cannot be used, and the "Activate License" dialog keeps appearing.
Solution
There can be a number of different reasons as to why a license is not being detected, or it is being detected, but cannot be used. The first step in diagnosing this type of issue is to right click on the title bar of the Activate License dialog that keeps showing and choose the option 'Advanced Details'. Examine the contents of the License log to see the reason why the license cannot be found or used. Also, check the License storage contents in the lower window, specifically the status of the license, to make sure that it is in an ENABLED state, check the Expiration Date etc.
