The offline installer is a full, self-contained .exe file (typically 450MB–550MB) that does not require an active internet connection during the setup process.

MSI does not prominently host offline installers on their main site, but you can access them via the BlueStacks offline installer mechanism. msi app player 64 bit offline installer upd
