Android and NW.Js export updates; Timeline improvements; Lots of bug fixes.
Doubt it.
So what I did is the following:
1. i exported my project using latest nwjs, and the default settings and downloaded it on my work computer (the mac)
2. i unarchived it, i opened the folder it made in the terminal and pasted the signing code shown in the guide, the terminal said something like "rewriting signature" and it finished in a few seconds
3. holding Control i right clicked the game application file and selected "Open"
4. it opened up the panel "are you sure you wanna blabla"
5. it worked
If you start the game without signing it, it will not work to sign it afterwards. You need to always start by unarchiving it again.
you beauty! :-D
it was almost certainly me not signing it initially, but trying to open, and then trying to do the signing again.
most definitely (as you say) you must do the process in the correct order.
thanks!!!
Glad it helped
