I am newbie to Flex.
I have downloaded and installed Flex builder 3 trying to debug a simple application.
When i click on debug in Flex builder i see following screen being displayed.
Which i click on yes i get this error
Appreciate if anyone can help me in resolving this.
For the debugger to work you have to have a "debug" version of the Flash player installed. (It's also interesting you seem to have Flash 10 installed and that might be part of the issue IIRC after I had a similar issue with the Flash Builder beta...)
Try uninstalling ALL versions of Flash from Add/Remove programs (Windows) and then install a debug version of the player. I'd try the Flash 9 ActiveX debug player first.
