- open a command prompt
- run the command “netstat -an > c:\test.txt”
- it creates the file test.txt with a list of all the ports open on your machine
- The Flash Builder 4 profiler runs on port 9999
- In my test.txt file I had a line that showed TCP 0.0.0.0:9999 0.0.0.0:0 LISTENING
- What you’ll need to look for is something similar for anything TCP listening on port 9999
- After identifying that port 9999 was already in use, it was a simple matter to change the port that the Flash Builder 4 Profiler uses
- Launch Flash Builder
- Go to Windows > Prefrences
- Go to Flash Builder > Profiler > Connections
- Change the port number to something that isn’t being used according to your test.txt file (we used 9997)
- Click Apply > Ok
- Close Flash Builder
- Launch Flash Builder
- Launch the Profiler
- WORKS!
I'm running Windows 7 64-bit (which they tried to tell me wasn't supported when the website says it is), also using Flash Player 10.1.
Booya!
