Flash Builder 4.5 won't run my application

I was running my application from Flash Builder 4.5.1 without any issues. (It is a Flex application that connects to .Net Web Services). However, something has changed recently in my configuration or project, because when I try to run the app with the play or debug button, I just get a grey screen. I can't even stop on any breakpoints.

Eventually (maybe 30 seconds), a message pops up like so: 'The Flash Builer failed to connect to the running application. Please make sure that you are running the debug version of Flash Player...'

  • I definitely have latest version of Flash Debug Player installed (11.1.102.55). I have tried uninstalling it and re-installing it.
  • I have tried cleaning and rebuilding my project.
  • I have tried switching to a different workspace and back again.
  • I have tried restarting the PC.

I am using the latest version of IE for testing.

I'm really stumped - has anybody got any ideas on how to solve this?

Thanks

Which browser are you using to test? – eterps
@eterps - Good point - I'm using latest version of IE. Is there a way of changing which browser it tries to run in? – JamesW

Have you tried deleting the html-template folder? This has caused issues for me in the past.

After it's deleted, when you try to build you will have a compiler error/warning about the missing folder. Right click and 'rebuild'.

There are some issues with compatability between 64 bit IE9, the 64-bit flash player, and 32-bit debugger. It seems like flash builder gets confused on which to use. I haven't seen any decent resolution yet in the Adobe forums for this particular issue other than use a different browser for testing.

To switch browsers, go to Window > Preferences... > General > Web Browser in Flash Builder. Select Firefox or Chrome.

In order to use Firefox, you need the Flash Debugger for Netscape compatable browsers installed. You can get that from Adobe here.

To use Chrome, you need to replace the built in flash player that is installed with Chrome with the debug player. Instructions from Adobe are here.
