Yesterday I was trying to install Steam on a new PlayOnLinux prefix but every time, after completing the download, the program crashed. There was a bug reported on Wine 1.7.7 which is now apparently fixed, but this does not explain the crashes which happened to me several times no matter what version of Wine I was using. I posted this information on reddit.com/r/linux_games (there was another thread on r/steam) asking what about older versions of Wine on PlayOnLinux and a guy wrote the following: Yeah, Steam won't work with older versions of Wine anymore. You'd have to backport the patch and recompile if you need to use an old version of Wine. Generally newer Wine is more compatible, if you find regressions it's helpful to submit bugs about them. Well, what do you guys think?
