Local AI Workbench Missing? Safe Reset Guide

If your Local AI Workbench has disappeared from your system, it is usually because the application was moved, the installation directory was renamed, or a background service failed to start. This guide walks you through finding it and performing a safe reset that preserves your models and data.

Why Your Workbench Disappeared

Local AI Workbench (a desktop app for running AI models offline) can vanish from your Start menu, desktop, or taskbar for several reasons. The most common causes are:

• Windows Update resetting app shortcuts or blocking the app’s background service.
• Antivirus or firewall quarantining the executable after a model update.
• Accidental move of the installation folder while the app was running.
• Corrupted user profile where the app’s configuration file is unreadable.
• Disk full preventing the app from writing its lock file on startup.

Before resetting anything, confirm the app is not just hidden. Press Win + S and type the app name. If it appears in search results, right-click it and select “Open file locationâ€� to see where it lives. If it does not appear, check the installation directory directly (usually C:\Users\[YourName]\AppData\Local\Programs\LocalAIWorkbench or C:\Program Files\LocalAIWorkbench).

Step 1: Backup Your Models and Data

A safe reset means you do not lose the models you downloaded (often several gigabytes) or your custom prompts and settings. Before doing anything else, back up these folders:

• Models directory (e.g., models subfolder in the install path, or a separate ~/.cache/localai on Linux).
• Config file (often config.json or settings.yaml in AppData\Roaming\LocalAIWorkbench).
• Log files (in the same AppData folder) – these help diagnose why it stopped working.

Copy these to an external drive or a different folder. If you are unsure where they are, open the app’s log file (if it still runs) or check the app’s documentation for the default data path.

Step 2: Uninstall and Reinstall the Application

Once your data is safe, uninstall the app through Settings > Apps > Installed apps (Windows) or by dragging it to the Trash (macOS). Then reinstall the latest version from the official source. This replaces all program files without touching your backed-up data folder.

After reinstalling, launch the app once. It will create a fresh config file. Close it, then copy your backed-up config.json and models folder back into the new data directory. This restores your previous setup without any corrupted files.

Step 3: Reset the Configuration Only

If you want to keep the app installed but suspect the config is corrupted, you can reset just the configuration. Navigate to the AppData folder (e.g., %APPDATA%\LocalAIWorkbench on Windows), rename config.json to config.json.bak, and restart the app. It will generate a default config. If the app works, you can manually re-enter your settings or compare the backup to find what broke.

This is safer than a full uninstall because your models stay in place. However, note that some settings like API keys or custom model paths will be lost, so keep the backup handy.

Common Problems After Reset

Even after a reset, you might see these issues:

• “Model not foundâ€� – the app cannot see your models. Check that the model path in settings points to the folder where your models actually are.
• “GPU not detectedâ€� – after a driver update, the app may need a restart. Ensure your graphics driver is current and that the app is set to use the correct device.
• “Port already in useâ€� – the local server port (often 8080) is occupied. Change the port in settings or kill the process using it (via Task Manager).
• Slow first start – the app may be re-indexing models. Give it a few minutes.

How to Avoid Future Disappearances

To prevent the app from vanishing again:

• Install it in a standard location (e.g., C:\Program Files) and do not move folders manually.
• Add an exception in your antivirus for the app’s install and data folders.
• Keep the app updated – older versions may conflict with newer OS updates.
• Regularly back up the config and models folder, especially before OS updates.

When to Consider a Full System Restore

If the app still does not appear after a clean reinstall and config reset, the issue may be deeper. Check Windows Event Viewer (under Windows Logs > Application) for errors from the app. If you see errors like “module not foundâ€� or “access denied,â€� a system file corruption could be the culprit. In that case, run sfc /scannow in an elevated Command Prompt, and if that finds nothing, consider a system restore point from before the issue started.

Only as a last resort, a full OS reset (keeping your files) can fix persistent issues, but it is heavy-handed and should not be needed for a single app.

Frequently Asked Questions

Will resetting delete my downloaded models?

No, if you back them up first. The reset only replaces program files or config. Models are stored separately and survive a normal uninstall/reinstall. Always copy the models folder to a safe location before any reset.

How do I find where my models are stored?

Open the app’s settings and look for “Model directoryâ€� or “Storage path.â€� If the app won’t open, search your system for files with .gguf or .bin extensions (common model formats). On Windows, check C:\Users\[You]\AppData\Local\LocalAIWorkbench\models.

Why does the app show in Task Manager but not in the window?

This usually means the background service is running but the UI failed to load. Try right-clicking the system tray icon (if present) and selecting “Show window.� If that fails, kill the process and restart the app. If it persists, the UI files may be corrupted – reinstall.

Can I reset without losing my custom prompts?

Yes. Custom prompts are usually stored in the config file or a separate prompts.json. Back up that file, and after resetting, copy it back. If the app uses a database, export your prompts through the app’s settings before resetting.

Is it safe to delete the app’s AppData folder entirely?

Only if you have backed up everything you need. Deleting that folder removes all settings, models, and logs. It is safe from a system perspective, but you will lose your data. Always move it to a backup location instead of deleting.
