From my experience, it's much easier if we install through anaconda.

Subject: [Kwant] Setup file for Windows...

Dear Users,
I am a new Kwant user. I want to learn this useful software. I could not find Kwant's ".exe" file for Windows. Do we need to compile the ".tar.gz" in Windows using Cygwin?
Any help would be welcomed.

Kind Regards,
