Fix Sync Agent installation problems on Windows and Linux.
App won't start
| Check | Action |
|---|---|
| OS version | Windows 10/11 or modern Linux required |
| Permissions | Try running as administrator (Windows) or with sudo for install (Linux) |
| Linux execute bit | AppImage or binary needs execute permissions: chmod +x |
| Antivirus | Temporarily allow the app if blocked |
Windows SmartScreen warning
"Windows protected your PC" is normal for apps without extended code signing:
- Click More info
- Click Run anyway
- Complete the installer
You can also verify the installer on VirusTotal for independent scan results from multiple antivirus engines. VirusTotal is a third-party service — a clean report does not replace Microsoft's SmartScreen prompt, but it can help confirm the file matches the official MyLMU release.
If VirusTotal has no report yet, download the installer from Dashboard → Sync Agent and use the Verify on VirusTotal link there, or upload the .exe manually on virustotal.com.
Linux package issues
| Issue | Solution |
|---|---|
| Missing dependencies | Install with your package manager's dependency resolver (apt -f install, etc.) |
| Wrong architecture | Download the package matching your system (x64) |
| Permission denied | Use sudo for system-wide install |
Corrupted install
- Uninstall the current version
- Download fresh from Dashboard → Sync Agent
- Reinstall and run First-time setup
