I ran into the exact same problem this morning after the launcher update
with the exact same problems trying to do the override, it just stops at “Check GUI version”, I wiped the prefix and tried to reinstall with the current launcher version provided on the website, and ran into the exact same problem, the problem reappeared on a fresh prefix.
I’m on gentoo with wine-staging-6.1
Nothing else on my system changed except for this launcher update; the only way I was able to fix this problem is dig up an old link to an old launcher download on reddit, and reinstall using that.
“EveLauncher-1850297.exe” does not have this problem. If I hadn’t have found a link to the old launcher on reddit I guess I would have been out of luck? I don’t know what else to do at this point except for refuse any further launcher updates and hope they don’t force it. None of the games I’ve played around that DLL seems to work, the built-in version crashes and the native version installed from winetricks or anywhere else gets this “Checking GUI version” message you can’t bypass.
Hopefully we get some more reports of this for more info, if they pushed an update today that borked it, it probably affects proton too, if it knocked out both ubuntu and gentoo versions of wine; though I don’t have steam installed on my system to test it, i’m using regular wine-staging not proton.
After this I would suggest being far more careful for anyone reading this; you don’t have much of a choice for game updates, but if it asks you to update the launcher DON’T DO IT until you’ve backed everything up.
