# Troubleshooting Barnet POS Manager Doesn't Open

**BARNET POS MANAGER DOESN’T OPEN**

If POS Manager does not launch, the most common cause is that multiple instances are already running in the background. This often happens from double-clicking the taskbar shortcut. **Taskbar shortcuts only need a single click**—double-clicking can accidentally open several hidden sessions.

To resolve this, close the extra instances using Task Manager.

* Scroll down to P, or
* Type “POS” in the Task Manager window to jump to POS Manager.

3. Right-click each POS Manager entry and select End Task.

Repeat until all POS Manager processes are closed.
