I'm rather confused about what I'm supposed to do with software to install through Lutris. Using Wine directly is more or less straighforward, and can be done easily through the terminal, or graphically. Lutris however, just has installer scripts that set up the environment that works for particular software.
Lutris has an option to manually add software already installed, where you can set the main executable file, but this doesn't help, as the software is not installed at this stage.
So if I have a disc, USB drive, or ISO that has been mounted, how am I meant to run the actual installer that installs the software?
