Don't see the relevance for this newsgroup, but here's an answer:
Not every program installed is installed through the Microsoft
Installer service, which is used by msi installers. For example,
innosetup uses its own installer engine and doesn't use windows
installer and therefore won't end up in the list of windows installer
programs.

The add/remove tool simply uses the registry to keep the list of
applications. The installer service writes to the registry, but so does
every other installer. That's the common denominator.
