AFAIK, .NET runtime is not needed for _native_ C++ applications. Just 
installing the runtime using the supplied merge modules (CRT + policy) 
should work just fine.

IIRC it is also _possible_ (even though perhaps not officially supported) to 
install the needed runtime DLLs in the same directory as the executable with 
a specially crafted external manifest.
