[Help]Install Flex SDK and create a Flex Application

Hi,


This is my first time using IntelliJ to develop Java so please explain for me if I wrote something wrong!


My issue:
I am trying to run a Flex Project with IntelliJ 15 but currently I don't know how to set up the Flex SDK. I tried to follow this guideline but it didn't help:
https://www.jetbrains.com/idea/help/preparing-for-actionscript-or-flex-application-development.html?search=FLEX


When clicked on + button to choose a SDK, it didn't show up Flex/AIR SDK in the Add New SDK list. It is also missing an option to create a Flash Project in Create New Project menu. Did I do something wrong installation or did JetBrains move Flex support to another IDE?

I also tried to follow this guideline by adding the path to the SDK folders but it didn't make any different:

Every help is appreciated!
