Could you provide more information? What version of the game is it exactly? When does the error happen? Right after double clicking the exe? Does it render the launcher or the main menu at all? What's your operating system? Have you tried running it again to see if it's a persistent issue? Most versions of SotE (including the latest 0.2) have two executables in their zip file. You have to use the one with Launcher in name. Additionally, on some systems, it may ask for administrative privileges, on others it may require them but fail to ask.
