Looks like you have multiple version of adb installed and they are not compatible with each other.
Make sure you use the latest version of Genymotion and Android Sdk (if installed), or that you don't have multiple version of Genymotion installed.
yup.. how do i uninstall those adb ? yup i have the latest version of Genymotion 2.4 , no android SDK installed. so do i need a Android SDK ? so where can i get it?
