Modeller for Windows is 32-bit software, so it should work with your 32-bit Python. But it's not tested on 64-bit Windows, so it's entirely possible that you could run into problems.

It shouldn't be necessary to set anything up to use Modeller from Python - when you install it the necessary registry keys are automatically installed. What setup did you do? Maybe that confused things.

I think you mean that _modeller.pyd in modlib/python2.6/ depends on libmodeller.dll in bin/, no? If you look at modlib/modeller/__init__.py, you'll see that when you "import modeller" it automatically modifies the Python path so that it can find _modeller.pyd, and the system PATH so that it can find the libmodeller DLL. So there is no need to do this manually. It might be worth putting some print statements in there to make sure this is working correctly on your system though.
