'Libgdx Installation gdx-setup.jar file missing

So I have watched several videos and read through many a forum post on installing libgdx with android development studio. Every time someone opens the gdx-setup.jar download there is a file within names gdx-setup.jar that you click on and brings up a setup project menu. However each time i download this file is missing and this is all I find within the download.

Here is a link to the picture of what I get when I open the libgdx download, (since I do not have the 10 reputation yet to include the picture in my post.) https://i.imgur.com/9DHTKVo.png

Just trying to get this framework setup so I can start learning more about using it in game development.



Solution 1:[1]

This documentation explains how to run the downloaded setup-gdx.jar to create a new project.

I guess, you're missing the part (or your OS is not picking up the correct application to run the jar file with [should be java]) how to run the downloaded jar:

Open up your command line tool, go to the download folder and run:

java -jar gdx-setup.jar

After that, if your OS has java or jre or jdk installed and configured correctly (JAVA_HOME variable set and exported) you should be able to see the UI.
