Is there a way to set DestinationFolder based upon a lookup value (specifically in Registry)? Can this value be set in a Custom action? I am not looking for a Special folder location like Program Files or User ApplicationData but a value that the application itself puts in registry. (This application is NOT always installed via InstallShield and this registry value tracks installation directory.)

Thanks in advance.

I hope this is clear - if not, I'll clarify.
