When trying to run the AeXSWDUsrUIWin.exe the error message "Error activating agent session 0: Invalid pointer (-2147467261)" appears. Also in the agent log files the following errors appear:

Launch client UI failed: Invalid pointer (-2147467261)
StartLocalSession: Unable to start user session Class not registered (-2147221164)

The agent appears to be installed and the Altiris Agent service is running.


While checking the Component Services (Administrator Tools > Component Services > Console Root > Component Services > Computer > My Computer), it was noticed that there was a red down pointing arrow on the icon. When trying to "Refresh all components," the following error message appeared:

The server catalog version is not supported. The catalog is either newer or older than this application and a common version for communication does not exist.

A screenshot of this error is shown below:


COM+ was found to be damaged in this environment. You can follow the Microsoft KB Article:315296 - "How to clean up a damaged COM+ catalog"  ( to repair this issue. A rebuild of the operating system may be necessary.

The Altiris Agent must be able to create COM+ objects to access the functions of the system. This allows the agent to communicate affectively with the Notification Server for items such as downloading packages.
