Detect Installed Applications

[behbeh]

I need to detect whether or not several applications are installed on a local PC. After researching the subject, I found a few API calls (GetFileVersionInfoSize and GetFileVersionInfo) that will give info if it finds the application in the DEFAULT path for that application (which has to be hard-coded).
Is there any other API function that I can use to query
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\APP PATHS\some_application.EXE ?

That is a registry key. There are a number of API functions for handling the registry. Two you might particularly helpful are the following:

RegEnumKey
RegQueryValueEx

Have a look at AssocQueryString. You pass it a registered file extension and it returns the path to the executable.
