Microsoft® Agent has been discontinued. The Microsoft® Agent web site has been reduced to a single page, but it's downloads are still available (for now). This page includes links to the setup programs for the various Microsoft® Agent components.
Note that on Windows Vista® or later, you have to run the setups "As Administrator" so they have sufficient permissions.
For Windows versions prior to Windows XP, you can go to the Agent 2.0 Core components page (or just download the agent server setup )
For Windows 7, Microsoft® Agent is available only by request . You need to request the hotfix for KB969168 , wait for a response from Microsoft, download the hotfix, and then install it.
