It has been brought to our attention that the "missing executable" error is occurring for those who have the game installed after updating. We had to upload the 1.1 update in a different way from before which changed the file path from the old version. The best solution we have, unfortunately, would be the following:
1. Uninstall the game.
2. In your file browser, Go (Installed drive, IE C:)...SteamLibrary\steamapps\common\The Masters Survival. You should also be able to get there by right clicking on the game in your Steam Library>Properties>Local Files>Click on the "Browse..." button to be taken directly to the game folder.
3. Delete the entire The Masters Survival folder.
4. Reinstall the game.
Luckily, your save data is stored separately in your user's Appdata folder in your C: drive, so no need to worry about losing your progress.
We apologize for the inconvenience :(
