title: Flash Builder cannot locate the required debugger version of Adobe Flash Player
body: <p>I'm running Flash Builder 4, with Flex 4.5.1 (also have 4.1, 4.0 and 3.5) and I receive this error when I debug...</p>
  
  <p>C:\Windows\SysWOW64\Macromed\Flash\NPSWF32.dll
  Flash Builder cannot locate the required debugger version of Adobe Flash Player. You might need to install the debugger version of the Flash Player or reinstall Flash Builder.
  Do you want to try to debug with the current version?</p>
  
  <p>I managed to fix this by installing the Flash Player 10 debugger, but... Flash player 11 is the latest and it causes the above error.</p>
  
  <p>Has anyone else experienced this issue and/or know how to fix this issue?</p>
  
  <p>Thanks</p>
