title: How do I upgrade from Eclipse PDT 2.2.0 build 20100617-1415 to fix the Zend Debugger ZF break-on-every-file bug?
body: <p>I have Eclipse PDT 2.2.0 and my Zend Debugger breaks at the start of every Zend Framework related file.  There is already another SO post <a href="https://stackoverflow.com/questions/3261038/zend-debugger-breaks-at-every-zend-framework-class">Zend Debugger breaks at every Zend Framework class</a> about that issue, and the solution was to update to a later build; however, I don't seem to be able to do that.</p>
  
  <p>After downloading the latest 2.2.0 All-in-One package from <a href="http://www.eclipse.org/pdt/downloads/" rel="nofollow noreferrer">http://www.eclipse.org/pdt/downloads/</a>, I've tried <strong>Help->Check for Updates</strong>, which fails and reports the following:</p>
  
  <blockquote>

  <p>Despite the "helpful" error message, I wasn't sure what to do, so I tried following the instructions mentioned in <a href="https://stackoverflow.com/questions/3261038/zend-debugger-breaks-at-every-zend-framework-class">Zend Debugger breaks at every Zend Framework class</a>.  I downloaded the recommended <a href="http://www.eclipse.org/pdt/downloads/?showAll=1&amp;hlbuild=M201006170734&amp;sortBy=date&amp;project=pdt#M201006170734" rel="nofollow noreferrer">201006170734</a> SDK as well as the latest <a href="http://www.eclipse.org/pdt/downloads/?showAll=1&amp;hlbuild=M201010110334&amp;sortBy=date&amp;project=pdt#M201010110334" rel="nofollow noreferrer">201010110334</a> SDK.</p>
  
  <p>Each time, I extracted the archives into <code>c:\program files\eclipse\dropins\</code> and started eclipse from the command line using the <code>--clean</code> flag.  Regardless, <strong>Help->About Eclipse</strong> still shows build id 20100617-1415 and my debugging sessions still break on every single Zend Framework file despite there not being any breakpoints set up in there.</p>
  
  <p>I can't believe it's this difficult to perform a simple upgrade.  Any suggestions?</p>
