--- Comment #6 from algebro@tuta.io --- I've confirmed that by moving `launchdarkly_client.pyd` one directory up into the parent (from C:\EVE\SharedCache\sisi\bin64 to C:\EVE\SharedCache\sisi), the game launches perfectly, which should confirm it's an issue with the search path in Wine. Still digging into things but if the wine devs have any input I'd be glad to hear it :)
Thanks for tolerating all of my rubber ducking!
