mentioned....addon it is for 2.2.4 and my CS now is 4.2.4

You'll have to port the addon from V2 toV4. There are many changes and you might have to rewrite it since a lot of the functionality has changed between V2 and V4.

Take default add-on ( e.g. banners) and compare the addon.xml and other files to see general changes between versions.

But we suggest you to ask your friend to make this adaptation
