Running from the the terminal, both from within the install folder and from desktop, by typing "HardwareSimulator.sh" in the terminal outputs the message "HardwareSimulator.sh: command not found"
This is normal. On Linux the current directory is not part of the PATH by default. To run the file you need to type ./HardwareSimulator.sh instead.
If that doesn't work, please try it as follows:
/bin/bash -x HardwareSimulator.sh
Then copy the output and paste it here, so we can see what's going on.
