Try getting the installed applications list through the registry. Check HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

This registry key holds some information ( Start->Run fetches commands from here ) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths This registry key also holds information on installed applications ("Open with" dialog fetches application names from here). HKEY_CLASSES_ROOT\Applications

Short of searching the entire disk(s), there's no sure-fire way of finding such information. You could look in places like HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths, but those are only as good as the applications themselves. An application is not required to update those registry keys.
