Common issues and how to fix them
Troubleshooting
Common issues you may encounter when installing or using Lite Suite, and how to resolve them.
SmartScreen Warning on Installer
Symptom: Windows shows "Windows protected your PC" when running the installer.
Cause: The installer is not yet code-signed with an EV certificate. This is normal for new software.
Fix:
- Click "More info" on the SmartScreen dialog
- Click "Run anyway"
- The installer will proceed normally
We are working on obtaining a code-signing certificate to eliminate this warning in future releases.
Python Not Found
Symptom: Python-based apps fail to launch with "Python not found" or "python3 is not recognized."
Fix:
- Run
lite doctorto check your Python installation - If Python is installed but not detected, set the path manually:
lite config set python_path "C:\path\to\python.exe" - If Python is not installed, Lite Suite can manage it for you:
lite install python - Restart LiteCore after making changes
GPU Not Detected
Symptom: AI/ML apps run slowly or show "No GPU detected, falling back to CPU."
Fix:
- Ensure you have an NVIDIA GPU with updated drivers (version 535+ recommended)
- Verify CUDA is available:
nvidia-smi - If CUDA is not installed, download it from NVIDIA's website
- Some apps may need a restart after driver updates
- Run
lite doctorto verify GPU detection
App Fails to Launch
Symptom: Clicking "Launch" on an app does nothing or shows an error.
Fix:
- Check the app logs in
%APPDATA%\LiteAISuite\logs\<app-name>.log - Run
lite doctorto check for missing dependencies - Try reinstalling the app:
lite uninstall <app-id> lite install <app-id> - If the issue persists, reach out on Discord
Port Already in Use
Symptom: A web-based app or MCP server fails to start with "EADDRINUSE" or "port already in use."
Fix:
- Check what is using the port:
netstat -ano | findstr :<port> - Stop the conflicting process, or change the port in the app's settings
- Each app's port can be configured in LiteCore Settings
Virtual Environment Corrupted
Symptom: Python apps crash immediately or show import errors.
Fix:
- Run the doctor command to detect and repair venv issues:
lite doctor - If auto-repair fails, manually recreate the venv:
lite uninstall <app-id> --purge lite install <app-id>
Installer Download Stalls
Symptom: The installer progress bar stops during app downloads.
Fix:
- Check your internet connection
- Try running the installer again -- it resumes partial downloads
- If behind a corporate proxy, configure it:
lite config set proxy "http://proxy:port" - Try downloading individual apps after initial install:
lite install <app-id>
