What is Windows Error Code ERROR_299?

ERROR_299 typically appears when Windows is unable to run a certain application or process due to issues with the executable file or a conflict within the system environment. This error may be linked to:

  • Corrupted or missing executable files.
  • Permissions and user account issues.
  • Software conflicts or outdated drivers.
  • Malware infections causing disruptions.

Understanding why ERROR_299 occurs sets the stage for an effective fix.


Step 1: Restart Your Computer

Sometimes, a simple reboot can resolve temporary glitches that cause ERROR_299. Before diving into more technical solutions, restart your PC:

  1. Click the Start menu.
  2. Select the Power button.
  3. Choose Restart.

After the system restarts, try running the application/process that led to ERROR_299 again. If the error persists, proceed to the next step.


Step 2: Run the Program as Administrator

Insufficient permissions can cause ERROR_299. Running the program with administrative privileges often fixes this:

  1. Locate the program or installation file that triggers ERROR_299.
  2. Right-click the file.
  3. Select Run as administrator.
  4. If prompted by User Account Control (UAC), click Yes.

If the error still appears, try the next method.


Step 3: Check for Malware and Viruses

Malware infections can interfere with system processes and files, leading to errors like ERROR_299. Running a thorough virus scan is critical:

  1. Open Windows Security by typing it in the Start menu.
  2. Navigate to Virus & threat protection.
  3. Click Quick scan or Full scan for a deeper analysis.
  4. Follow any recommended actions if threats are detected.

Alternatively, you can use trusted third-party antivirus software to scan your PC.


Step 4: Perform a System File Check (SFC)

Corrupted or missing system files often cause errors like ERROR_299. Windows has a built-in tool to fix these:

  1. Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
  2. Type the following command and press Enter:

    sfc /scannow

  3. Wait for the process to complete. It may take several minutes.
  4. If corrupted files are found, the utility will attempt to repair them automatically.
  5. Restart your PC and check if the error is resolved.


Step 5: Update Device Drivers

Outdated or incompatible drivers can also trigger ERROR_299. Here’s how to update them:

  1. Press Windows + X and click Device Manager.
  2. Look for devices with a yellow exclamation mark or the ones related to your problem application.
  3. Right-click the device and select Update driver.
  4. Choose Search automatically for updated driver software.
  5. Follow on-screen instructions to complete the update.
  6. Restart your PC when done.

For best results, you can visit the hardware manufacturer’s website and download the latest drivers directly.


Step 6: Reinstall the Problematic Software

If ERROR_299 occurs with a specific application, reinstalling it can fix corrupted or incomplete files:

  1. Open Settings (Windows + I).
  2. Go to Apps > Apps & features.
  3. Find the problematic program in the list.
  4. Click it and select Uninstall.
  5. Follow the prompts to remove the software.
  6. Download the latest version from the official site.
  7. Install the software and check for errors.


Step 7: Perform a Clean Boot

Conflicting startup programs or services might cause ERROR_299. Performing a clean boot helps isolate the issue:

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check Hide all Microsoft services.
  4. Click Disable all.
  5. Switch to the Startup tab and click Open Task Manager.
  6. Disable all startup items.
  7. Close Task Manager and click OK in the System Configuration window.
  8. Restart your PC.

Try running the application again — if it works without error, enable services/startup items one-by-one to identify the culprit.


Step 8: Restore Your System to an Earlier Point

If ERROR_299 started recently, restoring your system to a previous stable state might help:

  1. Type Create a restore point in the search box and press Enter.
  2. Click System Restore.
  3. Choose a restore point dated before the error appeared.
  4. Follow the instructions to complete the restoration.
  5. Restart and test your system.

Note: Make sure to save your work as this process may undo recent changes.


When to Seek Professional Help

If you’ve tried all of these steps and ERROR_299 persists, it might be time to contact technical support or a professional technician. There could be deeper system issues or hardware problems that require advanced diagnostics.
