I am trying to debug a Flash Web Application using Flash Builder 4. However, I keep getting this error:

Unable to Connect

Unable to connect to the application to fetch profile data. Please try profiling the application again.

I am using Internet Explorer 8 (the same problem also occurs with Internet Explorer 7) with Adobe Flash Player 10.1.102.64 (the Debug Player). In other words, I installed the latest of everything.

For my launch configuration, I have used the path to an HTML file. This works fine for debugging but does not seem to work for profiling.

What is the problem here?

Have you installed the debug version of Flash Player?

  • Yes, I'm using the Debug Player. I checked this on the page you gave. – Paul Reiners Jan 31 '11 at 19:58
  • Have you tried changing the port to connect to the profiler? It might be blocked by your firewall. You can change it in Window->Preferences->Flex->Profiler – Florian F Jan 31 '11 at 21:10

You have to use Version 10.0 of the Flash player (the debug version). Version 10.1 does not work with the profiler.

try checking your output folder for the build is pointing to where you expect (and thus can see its dependencies)
