Solution: Disable manually the Google Chrome integrated Flash Player plug-in.

  2. Type in the URL  "about:plugins" + enter
  3. Find the Flash plugin and expand the section by clicking the "+Details"
  4. In the expanded flash section find and disable the Flash Player that use the "gcswf32.dll"
  5. That's it, the Google Chrome should use now the Flash Player Plugin content debugger.
