A question that seems to pop up from time to time is where old, archived versions of Macromedia Flash Communication Server or Adobe Flash Media Server can be downloaded from. Sometimes people need to test legacy applications or simply own an old license but cannot find the installer anymore.
You are in luck. A little known fact is that all the software updaters for both FCS and FMS are in fact fully fledged installers - the title 'updater' is a bit misleading. Yes, they do update a previous version but they do so by effectively uninstalling the old version and reinstalling the new one.
Therefore if you need to obtain one of those legacy installers you can do so from Adobe's FMS Updaters page.
Scroll down - and back in time- to access all versions back to FCS 1.0. Ahhh... those were the days, eh?
