After installing the latest Titanium Studio (3.3.0) and Android SDK (4.4)- on Windows 7 (both 32 and 64bit) I was unable to get the Android emulators to start from Titanium. If I manually started the emulator from the Android tools - Titanium Studio would not communicate with it when running my "Hello Titanium" app.
Pressing Run and selecting my target emulator - the console would just show a starting line and then nothing would happen (no errors, no progress).
I researched all the other topics and including the one with the "simlink" solutions - none would help.
The solution was to use TaskManger, processes page - sorted alphabetically - and to manually kill the top "cmd" process from the list. After this - Studio would continue and my application would run in the emulator.
Seems as if a cmd is getting stuck and not returning.
