For this How To I am going to be using the dummy name “example.run”. You should replace this with the name of the file you are trying to install.
1. Open a terminal. In Gnome the terminal is found in Applications>Accessories>Terminal.
2. Navigate to the directory of the .run file. For this example, I have mine on the desktop so I would type in “cd ~/Desktop” and press enter.
3. Type “chmod +x example.run” (press enter).
4. Now type “./example.run”, press enter, and the installer will run.
