I am now running Dreamweaver CC (2015). I downloaded the latest MySQLi extension (1.0.4) update and tried to install with Extension Manager CC. Just so we're sure it was the MySQLi104.zxp But, when I do, I get this...
Error: "This extension can not be installed, it requires Dreamweaver 9 or greater"
Just to recap;
DW = Dreamweaver CC (Release 2015.0 - Build 7714)
EM = Extension Manager CC (Version: 188.8.131.52)
MySQLi104.zxp Won't install - See Error Above
WAeCart611.zxp Won't install - See Error Above
