How to update NWJS to latest unofficial version?

Hi,

I have C2 and would like to manually do an update to latest nwjs version.

I already replaced nwjs in nwjsforc2 folder recently, but it was almost never stopping background processes after exiting the program. So I figured there must be some things that need to be done in order to adopt it for c2. Anyone knows how to do it?

Thanks

Ashley
