I cannot access APM from my desktop and received the following error message: "Connection to the server has been denied due to SELECTServer licensing problem. Please contact the administrator for resolution. License status is PROD ID:XXXX|Status=Expired".
This is likely due to a rogue thick-client installation that doesn’t have its Bentley licensing registry updating. The approach we recommend is to remove the thick-client from the end-user and force him/her to use the smart-client installation instead. We don’t recommend that thick-clients be installed on any machines other than the server itself and even in those cases only used by application administrators. End-user needs should be met by the smart-client and it is far easier to manage.
If you don’t get rid of these rogue thick-client installs then you’re going to continually be having these sorts of issues pop-up. There is no real reason for a thick-client to be installed on an end-user machine because the only thing that the thick-client differs in functionality wise from the smart-client is in setting up services, customizing the application and editing securities which is dangerous functionality if left open to non-admins.
If this issue is happening on a server's thick-client installation then you may need retry activating the thick-client installation, see the following:
