Please be more explicit about what you know and what you guess.

Do you just mean that there are no errors displayed during the build?

What is not there?  Your executable, or Python27.dll ?  And exactly what 
folder(s) are you looking?

Python27.dll does not deploy your app.  Your app loads Python27.dll.

You can search for a file in Windows by doing something like:

      dir /s c:\somefile.dll

at a cmd prompt.  Does that find whatever file you're seeking?

When I ran Windows, I had written a simple utility that searched the 
PATH for a specified file.  I called it which.bat  to match the Linux 
equivalent.


I don't run Windows very often, but on my wife's machine I see 
python27.dll in

     c:\windows\syswow64

That's on a Windows7 machine running 64bit version.  Location will be 
different on various versions of Windows.

You can look to see where the system thinks the Python executable is 
located by doing

     ftype .py
and seeing what it shows.  Mine shows Python.File

   Then do
     assoc  Python.File

to see an actual path.
