Errors on LibGDX tutorial-Collection of common programming errors

I get the following errors on the LibGDX tutorial “Simple App”

Exception in thread “main” java.lang.UnsatisfiedLinkError: no gdx64 in java.library.path at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at com.badlogic.gdx.utils.GdxNativesLoader.load(GdxNativesLoader.java:118) at com.badlogic.gdx.backends.lwjgl.LwjglNativesLoader.load(LwjglNativesLoader.java:41) at com.badlogic.gdx.backends.lwjgl.LwjglApplication.(LwjglApplication.java:52) at com.badlogic.drop.DesktopGame.main(DesktopGame.java:7)

I copied and pasted the final code onto the project, but I don’t know why it wont run.

Whats the problem? Is it the project set-up?
