We are trying to setup an emulator in our PC to test some android apps. We are trying to setup Genymotion in keep getting errors such as "unable to start the virtual device", "virtualbox cannot start the virtual device". We have VirtualBox and PC has AmdP340/3gb ram/Windows 7 64b/AtiHD4200. What are we missing? Should we use another rather than Genymotion? Please Advice.
