Queued Components (QC) rely on Microsoft Message Queue Server (MSMQ) as a transport. To use QC you must have MSMQ installed. If you do not have MSMQ installed, when you try to set the Queued option for the COM+ application from the Queuing tab, the following error message is returned:
Either MSMQ is not installed or not running or this application is not set to run as a queued application.
