I am using a Dual Core 2.2Ghz computer (Intel), 2GB RAM with Windows 7 Ultimate SP 1. I have installed Windroy (Android emulator) on my PC. However, it doesn't work. After starting command box, I suddenly get White Screen and program stops there. Windroy fails to run on my PC. What could be the reason/solution? Does Windroy requires a graphic card? If yes, which one would be suitable? Can Windroy run without a graphic card?
