I have been trying to install Auto Accept Agent with error. We are runnning Exchange 2003 SP2 v6.5.7638.1 on three nodes cluster. Failed to install the Exchange 2003 Auto Accept Agent on to the node with Event Error: Event ID: 11722 Source: MsiInstaller Description: Product Auto Accept Agent -- Error 1722. This is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action CA_AutoAcceptInstaller.install, location: C:\Program Files\Exchsrvr\AAA\Bin\AutoAcceptInstaller.exe, command: Install 5. The Auto accept agent is download from the Micrsoft website. version v6.5.7618.0 Is this a compatibility issue between Exchange server and Auto accept agent? or is there a solution for this issue?

Dont know whether to reply this old forum. Restarting Distributed Transaction Coordinator service and reinstalling will fix this issue. few reports below http://www.ms-news.net/f1246/auto-accept-agent-autoaccept-msi-fails-to-install-10812600.html
