Curious. Sigil-0.9.9-Windows-x64-Setup.exe tends to fail downloading. I only managed to achieve it through an Opera extension (chrome, firefox both said no).
It also will not install (Win 10). Windows defender finds Win32/Fuerboos.B!cl trojan. Strange, though, that it will not allow me to install even with a "virus" with antivirus turned off.
This is directly from github:

Anyone else experiencing this?
