Hello everyone,

I just installed Android Studio and I'm following thenewboston tutorials on App Development. The problem I'm facing is that I cannot launch the virtual device. I'm starting AVD manager and when I click on the pre installed virtual device, it does not start. Nothing happens. Just the location of emulator and "netdelay none -netspeed full -avd Nexus_5_API_21" appears on the clipboard below. I would be grateful if you help me on this. 

Looking Forward.
