The Messenger executable comes with the WebSpeed Transaction Server. The Messenger is installed in the scripts directory of the Web server, which you specify during an OpenEdge installation.
If you install the WebSpeed Transaction Server on an operating system that is different from the operating system that runs your Web server, you need to download a compatible Messenger. Access the Progress Software Download Center and log in to your account at
http://www.progress.com/esd. Navigate to the WebSpeed Messenger download page by selecting Download Software and then Progress® Deployment Components. This is necessary because you must install a Messenger that is compatible with the Web server's operating system. For example, if your Web server is CGI-compatible and runs in Windows, you must install a CGI Messenger that can run in Windows.
