Trying to install new licenses results in errors:
No licenses are able to be installed. Issues with Altiris solutions, such as the Helpdesk not being able to create new incidents, may also occur. Reviewing the Altiris log, licensing errors appear such as the following "Unable to retrieve license information".
Removing and re-installing licenses fails to resolve the issue.
Logs have error : Class not registered
The Notification Server Licensing DLL has become corrupted.
Perform a repair install of the Notification Server and its hotfix. Note: This will bring down the Altiris services and functionality while thisl solution is being performed.
