I am new to blackberry development and ran into this problem several times and cannot find a solution.
When I try to run an empty cascades project just with a simple HelloWorld label I get the following error
Deployment Failed: Info: Sending request: Install and Launch
Info: Action: Install and Launch
Info: Debug native: on
Info: File size: 190910
Info: Installing com.example.HelloWorld.testDev__HelloWorld7d1bfe91...
Info: Processing 190910 bytes
I'm using Momentics, VMware running BB10 Dev Alpha Sim and followed all the instructions here. http://developer.blackberry.com/cascades/documentation/getting_started/setting_up.html
I made sure my build config is set to Simulator-Debug and not even the example projects are able to run on the simulator.
Edit: I am not sure if this bit of info helps but when I try to run the application, the Progress hangs at 91% before the error dialog appears.
