Hi Christoph, Thanks for your support! I am perplexed regarding my attempts at installing kwant on windows. TinyArray is functional and the import for TinyArray also calls a DLL file with a .pyd extension. TinyArray demonstrates that my installation can find and does load DLL files from within Jupyter notebook. The log file for kwant install was not that informative. I did however uninstall kwant and reinstall kwant. The uninstall log is more informative. I've attached some PNG files and the log files for your review. For installation, I executed from CLIpip -v --log log_kwantInstall.txt install --no-deps kwant-1.1.1-cp27-none-win_amd64.whl Again, thanks for your time reviewing my particular install issue, and best regards.

This is the extension module that is created from the source file kwant/linalg/lapack.pyx. On Windows it should have the file name kwant/linalg/lapack.dll, I believe. Can you tell us how exactly you installed Kwant? Are you building Kwant yourself (i.e. using setup.py or pip)? Can you provide a log of installation?
