Best way to install Halion 5/Halion Sonic 2 from ISO.

Hi Gang

I want to install Halion 5 and Halion Sonic 2 from ISO files what is the best practise?

Also can the Halion 5/Sonic 2 content be installed to an external drive during installation?


Edit…OK all sorted, wow it’s dead around here, Halion is great and so underrated.
