When starting the game, a red warning message may appear

This is an indication that the game did not get permission from Windows to write to the directory in the error message.
The primary causes for this are
- The user does not have authority from Windows to do so. This may be becase the user does not have the correct privileges or may not be the owner of the directory. This can happen if multiple uses share one computer with different login credentials, for instance.
- The installed antivirus program has prevented access to the directory. A message may have been logged. In this instance, follow procedures for your particular version of antivirus or anti-malware to whitelist the game.
