Note that there is a later version of the Visual C++ 2008 Redistributable package: SP1. However, both the SP1 and the earlier release don't install the DLLs into the path. As the download page says (my emphasis):

This package installs runtime components of C Runtime (CRT), Standard C++, ATL, MFC, OpenMP and MSDIA libraries. For libraries that support side-by-side deployment model (CRT, SCL, ATL, MFC, OpenMP) they are installed into the native assembly cache, also called WinSxS folder, on versions of Windows operating system that support side-by-side assemblies.

You will probably find these files in the %WINDIR%\WinSxS folder and not in the path.What I think you need to do is incorporate the manifest information for the relevant DLLs (found in %WINDIR%\WinSxS\Manifests) into your setup.py. I added the following section:

immediately after the existing section, and rebuilt the exe: it ran without problems. Note: depending on exactly what version of the Visual C++ files you installed, the above info may not be exactly correct. Look at the manifests on your system and use the correct version, publicKeyToken etc.

Alternatively, look at this answer for how to deploy the DLLs with your application (as opposed to assuming they already exist on the target system). Oh ... I see you asked that original question ;-)
