|Home > Model Shell Commands > License checking messages from Model Shell and ISIM systems|
The license checking messages appear in the stderr and stdout outputs, and are useful for the detection and diagnosis of licensing issues.
The model_shell and isim_system executables return a status value when they exit:
For exit status 1, parse the stderr output. A message might, for example, appear in the GUI with other WARNING, ERROR or Fatal Error messages. See the lines that follow for more information from the license checking module. When a license is about to expire, Model Shell prints a warning message to stdout, but the simulation still starts correctly.
ERROR: License check failed! Either the license file or the license server could not be found. Please set the environment variable 'ARMLMD_LICENSE_FILE' to your license file location or refer to the ARM_FLEXnet_Guide for instructions on where to obtain a license file, where to install the license file, and how to setup a license server.
