  • Restart your PC: Sometimes, a simple reboot clears temporary glitches that cause errors.
  • Update Windows 11: Keeping your operating system up to date ensures compatibility and fixes many known issues.
  • Close background programs: Other applications may interfere with the game. Close unnecessary apps to free system resources.

Step 1: Verify Game Files Integrity

One common cause of the EFEAB30C error is corrupted or missing game files. Verifying the integrity of game files through your game client (Steam or Epic Games Launcher) helps fix this by replacing damaged files.

How to verify files on Steam:

  2. Right-click on NBA 2K17 and select Properties.
  3. Click the Local Files tab.
  4. Click Verify Integrity of Game Files.
  5. Wait for the process to complete, then try launching the game again.

This step is essential because damaged files can cause crashes or errors during startup.

Step 2: Run NBA 2K17 as Administrator

Important: Only disable security software briefly for testing, and re-enable it afterward to keep your PC protected.

How to disable Windows Defender Firewall:

  2. Click Firewall & network protection.
  3. Select your active network.

If the game works after disabling security software, add NBA 2K17 as an exception or whitelist it in your antivirus/firewall settings.

Step 4: Update Graphics Drivers

Outdated or incompatible graphics card drivers can cause game errors. Updating your GPU drivers ensures better performance and fixes bugs.

How to update drivers:

  1. Press Win + X and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click your graphics card and select Update driver.
  4. Choose Search automatically for drivers.
  5. Follow any prompts to install updates, then restart your PC.

You can also visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) to download the latest drivers manually.

Step 5: Adjust Compatibility Settings

If NBA 2K17 was designed for an earlier version of Windows, running it in compatibility mode can resolve errors on Windows 11.

To enable compatibility mode:

  1. Right-click the NBA 2K17 executable file and select Properties.
