So I did a bit more digging and I found this -> https://developer.blackberry.com/html5/ ... ry_10.html
This is also out of date. When I did the signing it told me to go here.
C:\Program Files\Research In Motion\BlackBerry 10 WebWorks SDK <version>\dependencies\tools\bin
Whereas the new location is here.
C:\Program Files\BlackBerry\BB10 WebWorks SDK 184.108.40.206\cordova-blackberry\bin\dependencies\bb-tools\bin
I managed to do the signing via command line. So assumed I could now skip the "Click here to install code signing keys" part. However, I still need the WebWorks install path to export.
I'm pretty frustrated right now :/
