3. Interface Scaling Issues (High DPI)

On modern 4K laptops, WinOLS can appear tiny or blurred.

  • Fix: Right-click the WinOLS desktop shortcut -> Properties -> Compatibility -> Change high DPI settings -> Check "Override high DPI scaling behavior" and select "System".

5. Troubleshooting Common Issues

  • "Dongle not found" Error: This indicates the software cannot see the security key.
    • Solution: Re-install the Sentinel drivers. Check if the dongle is plugged in. If using an emulator, ensure the "Dongle Emulator" service is running in the background.
  • WinOLS crashes on startup:
    • Solution: This is often due to missing .NET Frameworks or C++ Redistributables. Install the latest Microsoft Visual C++ Redistributables (x86 and x64) and .NET Framework 3.5/4.8.
  • Maps are not detected:
    • Solution: Ensure the WinOLS database is updated. Go to the update manager or manually copy the latest .db files into the installation folder. Map recognition relies heavily on these databases.
  • Virus Detection:
    • Solution: Security patches and emulators often trigger antivirus false positives. You must add the WinOLS folder to your antivirus "Exclusions" list.
