  1. Open a terminal and log in as root by typing su -
  2. Change into the directory which contains the installer and start the installation assistant by typing ./MLDesigner-4.X.X.xxxx-ARCH-setup (where ARCH is [x86|x86_64]-linux-gcc[MAJOR GCC VERSION]).
  3. The start dialog appears with a couple of options
    1. Install: Click the item MLDesigner Setup Assistant to proceed with the installation.
    2. Remove: If any older version of MLDesigner is currently installed on your system, the item Remove MLDesigner Software is active. We recommend to uninstall older versions before proceeding with the installation.

  6. Now, the configuration of your MLDesigner installation is displayed. Please select the components you wish to be included in the final installation of MLDesigner. If in doubt, the default settings should be suitable for general use. To complete this step, click on the Next button.
  7. The next step automatically checks for required system components and determines the compatibility of MLDesigner with your operating system. Please refer to section System requirements if one or more tests fail. Finally, click on the Next button to start the installation procedure.
  8. Now, all files are copied to the given installation directory. This may take a while. The progress bar informs about the current installation task.
  9. When the installation assistant has finished, the next dialog window is displayed automatically.
  10. Please complete with a click to the Close button.


Installation assistant fails to start

Not all environments allow graphical applications to be run as root (for example, the Wayland display server). It is therefore necessary to allow this explicitly by using xhost.

To allow root to run graphical applications, type in a terminal:

  1. xhost si:localuser:root

After that, you should be able to continue with the procedure described above. When the installation is finished you can again remove the permission to run graphical applications as root by typing:

  1. xhost -si:localuser:root
