Error: “The program tried to start up the CPR Listener on the following TCP/IP port numbers but all of them seem to be unavailable. Checked port numbers: 5650-6672”

ps aux | grep -i codemeter
ps aux | grep -i wibu

If multiple instances are running, kill them:

sudo pkill -f CodeMeter
sudo pkill -f wibu

Restart the CodeMeter daemon:

sudo /Library/CodeMeter/bin/codemetercc restart

sudo lsof -i :5650-6672

This will identify any process squatting on the required ports.

sudo launchctl stop com.wibu.CodeMeter.daemon
sudo launchctl start com.wibu.CodeMeter.daemon

• Go to System Settings → Network → Firewall → Options
• Ensure CodeMeter is not being blocked
• Firewall prompts can be silently missed after macOS updates

• Go to System Settings → Privacy & Security
• Look for CodeMeter or Wibu entries and ensure they have network access

1. Uninstall TopSpin completely
2. Remove CodeMeter manually:

sudo rm -rf /Library/CodeMeter/
# Also remove LaunchDaemons
sudo rm /Library/LaunchDaemons/*codemeter*
sudo rm /Library/LaunchDaemons/*wibu*

1. Reboot
2. Reinstall TopSpin fresh
