  <p>but this time it isn't working and also tried to kill <strong>adb.exe *32</strong> process from windows task manager. It disappears from the process list and again gets there.  So, as a result i cant run any app from eclipse. 
  the erros is:</p>
  
  <pre><code>Please ensure that adb is correctly located at 'D:\DevTools Backup\AndroidSDK\sdk\platform-tools\adb.exe' and can be executed.
