This Delphi example application from 2003 is a simple way of checking what COM servers are installed on the computer the application is running from. It uses registry settings to retrieve information about the classid, progid, location and names of the COMs installed, and is a good example of how to use the TRegistry class and the TListView class.

The application could easily be extended to have custom code to uninstall and install COMs. Built using Delphi 5.
