so you can download the zip file but you would have to launch that folder as an mounted cdrom drive
a tool such as magic disk in tool/2001-2015 can be used to mount a folder(zip file expanded) then run game
OR-----
download the ISO file , right click and select mount run "autorun.exe" for main menu
install. and use the icon created during install
--
you must have the iso mounted to play and avoid DRM license issues.
