libgdx setup ui jar file not executing

Question

I double click, nothing happens.

I opened cmd from the foler, did: java gdx-setup-ui.jar and I get:

Error: Could not find or load main class gdx-setup-ui.jar

I just updated the JRE recently, to 1.7.0_45, and JDK is 1.6.0_18

I used to create libgdx projects before also, and it used to work. I'm using Windows Vista.

Answer 1

It should work by just double clicking, though I also noticed that it's buggy sometimes in Windows.

Use java -jar gdx-setup-ui.jar (with -jar ) to execute it manually.

Answer 2

You need to download the JRE to open .jar file. Here is the link http://www.computerhope.com/issues/ch001343.htm
