Proton (Linux) doesn't work due to Microsoft Visual C++ Runtime error
Thank you @Lord Asteyr :https://steamcommunity.com/app/865540/discussions/0/2849047119419340633/
Download and install latest GloriousEggroll version: https://github.com/GloriousEggroll/proton-ge-custom/releases
Then install Protontricks: https://github.com/Matoking/protontricks
Then set the GE proton version to run Playne in the compatibility tab
Then use Protontricks to install the 2019 Visual C++ runtime into the Playne wineprefix when it prompts a selection I was able to successfully run this latest update having done that.
