If you see this error, it is because A-Shell is trying to run but cannot find or process the required initialization file (normally "miame.ini"). This would normally indicate that the "-i <ini file spec>" argument on the launch command line is missing or incorrect. See Specify Ini File for related information.
A similar and related error message for a missing ini file is shown below. This normally occurs if A-Shell has previously been set up properly and has run as expected, but the ini file has been moved or renamed.
