Python: Installing OmniOrbpy in Windows64(Windows 7) environment

I'd like to experiment with a Python (v2.7) app accessing a CORBA API, but I keep going around in circles about which OmniOrb pieces are necessary and where they should be placed.

I've downloaded omniORBpy-4.2.0-win64-py27 which I thought should have contained the bits I needed.

Is is as simple as adding the files in the bin\x86_win32 directory into my Python lib\Site-packages directory ?

I've found conflicting information about using the PYTHONPATH environment variable (I don't have one now), is it necessary?

With help from Duncan Grisby.

1. The version of omniORBpy must match the Win32/Win64 status of your environment.
2. Copy the distribution to a directory (I used python27/lib/site-packages/omniORB
3. Add to or create a PYTHONPATH environment variable that points to ../omniORB/lib/python and ../omniORB/lib/x86_win32
4. Merge the contents of sample.reg into your Windows Registry
5. Add an explicit PATH environment entry to ../omniORB/bin/x86_win32

Please note that omniORB is case sensitive for the paths, even though Windows is not.
