I’m assuming that you’ve downloaded the Android SDK from Google. If not, download it. http://developer.android.com/sdk/index.html

The error you’re getting suggests that the program adb.exe is missing from the c:sdktools directory on your computer. Try opening up My Computer, then the C drive, then the sdk folder and then the tools folder and looe to see that the adb program is there.

If it isn’t there, then download the SDK again and re-copy the files from the zip to the c:sdk folder. If the sdk folder doesn’t exist at all… download the Android SDK, unzip it to a directory called sdk, then move that directory to your c drive. Then you should have adb in c:sdktools.
