title: ADB is not starting (no error message)
body: <p>I am trying to run adb. When I run : "adb start-server" it hangs during a while, and then no message.</p>
  
  <p>After that the command "adb get-state" receive the answer "error: protocol fault (no status)"
  If I run then "adb kill-server" the answer is "* server not running *"</p>
  
  <p>I am using windows 7. An admin has elevated my rights to local admin, but it did not solve anything. </p>
  
  <p>I used resources monitor to verify if any other app is using the ports of adb, but it is not the case.</p>
  
  <p>on <a href="https://developers.google.com/chrome-developer-tools/docs/remote-debugging" rel="noreferrer">https://developers.google.com/chrome-developer-tools/docs/remote-debugging</a>
  the step 3 indicates to "Enable USB Web debugging" under Settings > Advanced > DevTools.
  But on my test phone, there is no "advanced" category in the chrome settings. I couldn't find out either what is the version of chrome installed.</p>
  
  <p>Somewhere on the web I saw a suggestion to change the rights of "tmp/android/" to allow read &amp; write for all users, but in C:\Users\me\AppData\Local\Android\android-sdk\temp there is no android folder.</p>
  
  <p>So I am pretty desperate now, any help would be immensely appreciated.</p>
  
  <p>thanks</p>

  <p><strong>EDIT 1</strong>: I could't find "Enable USB Web debugging" because it was "android browser" and not chrome (a bit ridiculous yes). I did not know that. Using another device with a proper chrome installed, I could check the option there, but adb is still crashing at startup.</p>
  
  <p><strong>EDIT 2</strong>: I did a wild guess that there was some Write issue with the platform-tools folder.
  So I uninstalled everything using the sdk manager, I deleted the whole adt-bundle-windows-x86_64. Then I unzipped it elsewhere, on c:. Strange thing is, when I launch SDKManager.exe, several packages are already marked as installed :</p>
  
  <ul>
  <li>Tools>Android SDK Tools</li>
  <li>Tools>Android SDK Plateform-tools</li>
  <li>Android 4.2.2>SDK Plateform</li>
  <li>Android 4.2.2>ARM EABI v7a System Image</li>
  <li>Extras>Android Support Library</li>
  </ul>
  
  <p>I tried deinstall them again, delete the folder, unzip again and re-install, but still same result. It seems that somehow, it is installed wrong, but refuses to uninstall properly. Anyone knows how to force the unistallation ?</p>
  
  <p><strong>EDIT 3</strong> :
  output of adb start-server after having used set ADB_TRACE=1</p>
