Hello, I am having exact same problem as Aaron. Mobile device Nexus 4. I am using Flash Professioanl CC latest version. I have installed SDK and driver for NEXUS 4 so that Windows 7 nicely recognizes it in the Device Manager. I also, just in case, made automatic search for the newest driver in the Device manager and got notification that I am using the latest version of the driver. Developer mode is switched on on NEXUS 4. Also there is a working connection between Flash CC and the mobile device because Flash CC recognizes the device and before publishing shows correct device ID. Although when I hit Publish button it creates .swf, but at the stage of publishing Flash CC crashes. It freezes and when after some waiting I try to close the publishing dialog Flash CC stops working.
I did follow the solution of Aaron Beall above by installing toolkit, even though I am not quite trust the publisher, but even this did not help.
Any help from Adobe?
Thanks
