After my initial problems, this now to works for me. I still don't
understand what went wrong initially, though.

I can a confirm this for the manifest included with OpenVPN 2.2.1 which
I had installed before:

    <assemblyIdentity
        type="win32"
        name="Microsoft.VC90.CRT"
        version="9.0.21022.8"
        processorArchitecture="x86"
        publicKeyToken="1fc8b3b9a1e18e3b"
    />

When Dependency Walker showed a reference from mxDateTime.pyd to the
32-bit version of MSVCR90.DLL, it always also showed a reference from
PYTHON27.DLL to the 64-bit version of MSVCR90.DLL.
