Solution:

I found libzmq.pyd located C:\Python27\Lib\site-packages\zmq. I copied it to C:\Python27\Lib\site-packages\zmq\backend\cython. Re-run pyinstaller.

Thanks rickyteng! Saved me quite a bit a time with this fix!

Actually, the current Pyinstaller with Python 3.6 on Windows 10 still have the same problem. The solution is still the same: copy libzmq.pyd from Python folder to zmq\backend\cython folder.

Anyone care to share their pyinstaller spec file?

Closing as old and not really a pyzmq issue. I also suspect that pyzmq 26, which has a single library that statically links libzmq on Windows will also not see this issue.
