Well, I'm not sure how exactly proton configures things, but as long as you have a proper copy of wine installed and 'wine' refers to that copy, not what Proton installed, those steps (in most of the cases) consist of going into the directory with game executable and running 'wine <executable name>'.
Unfortunately, doing that doesn't seem to just work, it's probably going to need some more fiddling to reproduce this problem with wine alone. This is the output I get from trying to run it straight from its directory: [vitorc@lambda:~/SteamGames/SteamLibrary/steamapps/common/Path of Exile]$ wine PathOfExileSteam.exe Application could not be started, or no application associated with the specified file. ShellExecuteEx failed: Bad EXE format for Z:\home\vitorc\SteamGames\SteamLibrary\steamapps\common\Path of Exile\PathOfExileSteam.exe. I noticed there was a second .exe in there so I tried it as well, but same result: [vitorc@lambda:~/SteamGames/SteamLibrary/steamapps/common/Path of Exile]$ wine PathOfExile_x64Steam.exe Application could not be started, or no application associated with the specified file. ShellExecuteEx failed: Bad EXE format for Z:\home\vitorc\SteamGames\SteamLibrary\steamapps\common\Path of Exile\PathOfExile_x64Steam.exe. For completeness' sake, this is on NixOS, and this is the version I'm using: [vitorc@lambda:~]$ wine --version wine-11.0 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
