Logi Options Plus Not Working | How to Fix it

If you are on a Mac, this is likely due to a specific “Expired Certificate” bug that hit Logitech users yesterday (Jan 7, 2026). If you are on Windows, it is usually a stuck background process.

Here is how to fix it based on your operating system:

Option 1: You are on Mac (Most Likely Cause)

A security certificate expired on Jan 7, 2026, causing the app to hang on the purple loading screen or crash for many users. The auto-updater inside the app won’t work because of this.

1. Download the Patch: You must manually download the new installer from the Logitech Support Website. Look for the version released Jan 7, 2026 (or later).

2. Install Over Existing: Run the installer. You do not need to uninstall the old one first; this patch will fix the broken backend files while keeping your mouse settings.

3. Check Permissions: If it opens but doesn’t “see” your mouse:

   • Go to System Settings > Privacy & Security > Input Monitoring.

   • Remove Logi Options+ (click the - button).

   • Add it back again (click +) and restart the app.

Option 2: You are on Windows

The app is likely stuck in a “zombie” state where the interface is closed but the background process is frozen.

The “Task Manager” Fix (Try this first):

1. Press Ctrl + Shift + Esc to open Task Manager.

2. Search for “Logi” in the top search bar.

3. Right-click and End Task on everything you see (e.g., Logi Options+ Agent, Logi Overlay, Logi Crashpad).

4. Relaunch the app as Administrator (Right-click the icon > Run as Administrator).

The “Clean” Reinstall (If the above fails):

Standard uninstalling often leaves the corrupted settings file behind.

1. Uninstall Logi Options+ via Settings.

2. Press Win + R, type %localappdata%, and press Enter.

3. Find the folder named LogiOptionsPlus and delete it. (Warning: This wipes your custom button mappings).

4. Reinstall the app fresh.

Common Issue: “Backend Connection Problem”

If you see a red error saying “Backend Connection Problem,” it means the service that talks to the mouse has crashed.

• Fix: Open the app. If it spins, leave it open. Toggle your Wi-Fi OFF and then ON. Surprisingly, this forces the app to re-ping its local server loop and often unfreezes it immediately.
