you can run android application very easily but supporting Application (Bluestack)
Bluestack apps player is windows based application . download bluestack and then you can run any android application. Bluestack coming in two form first is online installer and second is offline installer. Offline installer is better than online because in offline, you need only download one time approx (195 MB) file then you can run in any PC but in online,you need to download by installer very big data (this process takes very long time).
