I just figured it was extra information the OP could use;  finding the 
executable is a useful thing, even though different from finding the DLL.

Doesn't do much good to have the DLL only in the python directory, if 
you're going to load it in a default way from a C++ program.  Python.exe 
doesn't do much, it mainly parses the commandline and invokes the DLL. 
Other programs that want to call Python functions don't need the exe, 
and therefore count on the DLL being on the Windows path.

The OP sent me a private message saying:
    "Python.dll was found in my C:/Windows/SysWOW64 dir"

I responded and intended it to be posted to the list, but messed up. 
You should see it by now.
