If the software was installed with Windows Installer, then you can use the
Windows Installer API, which has the ability to list all installed programs,
features, and components, as well as version information and lots more. You
can call functions to uninstall what you need. See
http://msdn.microsoft.com/library/de..._installer.asp
If Windows Installer hasn't been used, the you could use the technique from
Jason (assuming the installer properly wrote to the registry - if the
install was home-brewed, you may not be able to uninstall it automatically).
