Troubleshoot Fing Desktop: Fing Service Not Found

If you see the error message Fing Service not Found when installing Fing Desktop, follow these steps:

Check Compatibility

Ensure you have the latest version of Fing. 

• Fing Desktop supports any version of Windows that is still within its extended support lifetime to the current version. Windows Server versions are not supported.
• Fing Desktop supports macOS Ventura and later to the current version.

Troubleshoot on Windows

1. Uninstall Wireshark if you use it. Wireshark uses NpCap library which may create a compatibility issue with Fing desktop.
2. Restart your PC.
3. If restarting your PC does not resolve the issue, do this:
   1. Enter 'cmd' to bring up the Command Prompt.
   2. Open the Command Prompt as administrator.
   3. Enter the stop service command: sc stop Fing.Agent.
   4. Enter the start service command: sc start Fing.Agent.

Troubleshoot on MAC

Starting with Fing Desktop 4.0.7, Fing's background agent uses Apple's recommended system service. We modernized how the Fing agent is installed on macOS to follow Apple's current security model.

You can start and stop the agent from System Settings on your macOS.

Applies to: Fing Desktop 4.0.7 and later on macOS

If you get the error message Service Not found, follow these steps to Update your Fing Desktop and if that does not solve the problem,  follow the steps to Stop and Start the Agent.

Update Fing Desktop

1. Update Fing Desktop through auto-update, or install the new version over your existing app.
2. When prompted, enter your administrator password.
3. When the macOS notification appears, allow Fing to run in the background.
4. Open System Settings > General > Login Items & Extensions.
5. Make sure Fing is switched on.
6. Wait about one minute. The agent will start automatically.

Installing Fing for the First Time

1. Install Fing Desktop as usual.
2. When the macOS notification appears, allow Fing to run in the background.
3. Open System Settings > General > Login Items & Extensions and make sure Fing is switched on.
4. Wait about one minute for the agent to start.

Start and Stop the Agent

• To stop the agent: open System Settings > General > Login Items & Extensions and switch Fing off.
• To start the agent: switch Fing on again. The agent starts within about a minute, with no reinstall needed.

Additional Troubleshooting Guidance

The agent isn't running after installing or updating
You most likely dismissed the macOS notification. Open System Settings > General > Login Items & Extensions, switch Fing on, and wait one minute. You don't need to reinstall.

The agent isn't responding right after restarting your Mac
This is expected. The agent waits until the Mac has been running for about 5 minutes before it starts. Wait a few minutes, then check again.

You cancelled the administrator password prompt during the update
Quit Fing and open it again. The prompt will reappear so the update can finish.

Fing is switched on but the agent still isn't working

1. Check that your Mac wasn't restarted in the last 5 minutes.
2. If it wasn't, switch Fing off, then on again in Login Items & Extensions, and wait one minute.
3. If the issue continues, contact Fing Support (details below).

The agent restarted by itself
This is normal. If the agent process stops unexpectedly, macOS restarts it automatically.
