Okay I got it working on my computer, macOS 10.12.4, Wineskin 2.6, Wine 2.6, Alpha 19.
I followed different steps though, what I did:
- Install steam in my empty wineskin using the winetricks menu
- Install Stonehearth through steam
- Switch to the 'legacy_vista' branch under the betas tab for Stonehearth in steam.
I didn't run any other script from the winetricks menu, just steam. You can then edit the wineskin to run the stonehearth exe directly without moving any files to bypass steam. Set Windows EXE to 'Program Files/Steam/steamapps/common/Stonehearth/Stonehearth.exe'
