  <p>I started getting errors in my Eclipse Workspace for several but not all of my projects.  I noticed is was the oldest projects.  I found help for the error, and built my own debug.keystore and changed the java build path to that folder.</p>
  
  <p>Now when I try to run any of the projects in an emulator I get this error:</p>
  
  <pre><code>[2011-04-19 10:11:20 - enga] Re-installation failed due to different application signatures.
  [2011-04-19 10:11:20 - enga] You must perform a full uninstall of the application. WARNING: This will remove the application data!
  [2011-04-19 10:11:20 - enga] Please execute 'adb uninstall com.engatest' in a shell.
  [2011-04-19 10:11:20 - enga] Launch canceled!
  </code></pre>
  
  <p>I tried removing the application from the menu in the emulator, got through the motions and drag it to the trash but it doesn't get removed.</p>
  
  <p>I tried running in terminal: <code>adb uninstall com.dwclogic.engatest</code>
  but the command wasn't found, adb probably not setup globally on my mac.  I am new to the Mac and am unsure how to get the execute path for this fixed but that's an whole other issue.</p>
  
  <p>where do I try running this command?  Is there any other ways to fix this problem.</p>
