How to use the downloaded extension objects in QlikView (not in QlikSense)???

[#1]

I've used QlikSense extensions by downloading them from brach. But now I want to use those extensions for QlikView as well.

For example: I've downloaded this Double Bar chart extension http://branch.qlik.com/projects/showthread.php?634-Double-Bar-Chart&p=2161#post2161

Now I want to use it in QlikView. How do I do that???

All the tutorials on the internet are only explaining how to double the pre-existing .qar file in the Examples folder but that will only give you 5 in-built extensions, but I want to download and use the new objects for QlikView. Should I copy that downloaded folder to some path in QlikView?? How to use them???

PLEASE HELP.
