port 4445 or 4444 is blocked Follow
When you want to perform recording, and the toolbar buttons are not enabled, then it might mean that the port 4444 or 4445 are blocked.
You can check that error in the Java console, in the log.
If the port is occupied by another service/process, that service must be stopped for the recording time only.
Find out what process is listening on 4445 port
netstat -ano | find "4445"
Then you get the process number, and you need to find the process name attached to it.
tasklist /fi "pid eq <process_id>"
Now you can stop that process for the recording time only.
