iso file not recognized

I'm using Parallels Desktop 17. I want to install ArcGIS Desktop version from .iso file but it says "problem mounting the file". I first downloaded it just normal on MacOS and thought that maybe that's why it wasn't working, but I tried to download it directly on windows over parallels and it's...

The iso file was downloaded directly from microsoft but isn't recognized as a valid iso file for parallel 10 file name: en_windows_10_education_version_1703_updated_march_2017_x64_dvd_10189297.iso
