It is possible to set it from command line (for example, "winetricks
winxp"
or "winetricks win98"), but it is better to install each program in
its own
Wine prefix (for example, "~/wine/mygame" or
"~/wine/microsoft-office").
Reasons are obvious: you can uninstall a program by deleting its prefix, you
can apply application-specific workarounds without affecting other programs,
and everything will work more reliably this way.
