How to Fix lci proxyumd32.dll Errors (Without Downloading the DLL File)

Downloading individual DLL files from third-party websites is risky and often introduces malware. Instead, you can fix the issue safely using built-in Windows utilities and clean driver reinstallations.

1. Run the Deployment Image Servicing and Management (DISM) Tool

This built-in tool repairs corrupt system images that might be causing driver conflicts.

  1. Press the Windows Key, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type the following command and press Enter: DISM.exe /Online /Cleanup-image /Restorehealth
  3. Wait for the process to complete (it may take several minutes).

2. Run the System File Checker (SFC)

The SFC utility scans and restores corrupted Windows system files automatically.

  1. Keep the Administrator Command Prompt open from the previous step.
  2. Type the following command and press Enter: sfc /scannow
  3. Restart your computer after the scan finishes.

3. Reinstall Your USB Display and Docking Station Drivers

Since this file belongs to your display adapter or docking station software, reinstalling the official hardware package will recreate the missing file safely.

  1. Right-click the Start Menu and select Device Manager.
  2. Expand the Display adapters or Universal Serial Bus controllers section.
  3. Look for your docking station, Fresco Logic, or DisplayLink device.
  4. Right-click it and select Uninstall device (check the box that says "Attempt to remove the driver for this device" if visible).
  5. Unplug your docking station or USB adapter, restart your PC, and plug the device back in. Windows will automatically reinstall the driver.

4. Roll Back a Recent Windows Update

If the error started appearing immediately after a Windows update, a temporary incompatibility might be the cause.

  1. Open Windows Settings (Win + I).
  2. Go to Update & Security > Windows Update.
  3. Click on Update history and select Uninstall updates.
  4. Locate the most recent update, click Uninstall, and restart your computer.
