Remember, patience is key while performing these fixes. Take your time to understand each step.

Quick Note: Prerequisites and Initial Checks

  • Restart Your PC: Sometimes, a simple restart can fix temporary glitches causing the error.
  • Check for Windows Updates: Ensure your system is fully updated by going to Settings > Windows Update. Updates often fix bugs and improve system stability.
  • Scan for Malware: Malicious software can interfere with files like cpx.exe. Run a full system scan using Windows Defender or any trusted antivirus.
  • Note the Error Details: If possible, write down any error messages or codes that appear when the error shows up. This information can help during troubleshooting.

Step 1: Run System File Checker (SFC) Scan

The System File Checker is a built-in Windows tool that scans for and repairs corrupted system files, including those related to cpx.exe.

Here’s how to run it:

  1. Click the Start button and type cmd.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the black Command Prompt window, type sfc /scannow and press Enter.
  4. Wait for the scan to complete. This might take several minutes.
  5. If any corrupted files are found, Windows will attempt to repair them automatically.
  6. Once done, restart your PC and check if the error persists.

Why this step is important: Corrupted or missing system files are common causes of executable errors. The SFC tool helps fix these files without needing a full reinstall.

Step 2: Use the Deployment Image Servicing and Management (DISM) Tool

If the SFC scan did not fix the problem, the next step is to use DISM. This tool repairs the Windows image, which can fix deeper issues.

To run DISM:

  1. Open Command Prompt as administrator again (same as Step 1).
  2. Type the following commands one by one, pressing Enter after each: 
    DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
  3. Wait for each command to finish before entering the next one.
  4. After the last command completes, restart your computer.

Why this helps: DISM repairs the system image used by Windows to restore system files, helping fix issues that SFC alone can’t resolve.

Step 3: Check and Repair cpx.exe File Location

The cpx.exe file might be missing or corrupted in its proper folder. To verify and fix this:

  1. Press Windows + E to open File Explorer.
  2. Navigate to the folder where cpx.exe is supposed to be located. This varies depending on the program using it, but often it’s in C:WindowsSystem32 or the software’s installation folder.
  3. If the file is missing, try reinstalling the related software or restoring the file from a backup.
  4. If the file is present but the error continues, right-click it, select Properties, and check the Details tab for any suspicious info.
  5. Run a virus scan specifically on this file to ensure it’s not infected.

Why this is necessary: The error often occurs if the executable is damaged, missing, or replaced by malware.

Step 4: Update or Reinstall the Related Application

If the problem is linked to a specific program using cpx.exe, updating or reinstalling that application can fix the issue.

  1. Identify the program causing the error by noting when the error appears (e.g., during startup or when launching a certain app).
  2. Visit the official website of that software and download the latest version.
  3. Uninstall the current version by going to Settings > Apps > Installed apps, finding the program, and clicking Uninstall.
  4. Restart your PC.
  5. Install the newly downloaded version.
  6. Check if the error still occurs.

Why update or reinstall: Software updates often include bug fixes. Reinstalling ensures all program files are clean and correctly placed.

Step 5: Perform a Clean Boot

A clean boot starts Windows with the minimum set of drivers and startup programs. This helps identify if third-party apps are causing the cpx.exe error.

To perform a clean boot:

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

Why this step helps: Conflicts with other software often cause executable errors. Clean boot isolates this by disabling possible problem programs.

Alternative: Use System Restore to Undo Recent Changes

If you started seeing the error recently, you can try restoring your system to a previous state when it worked fine.

  1. Press Windows + S and type System Restore.
  2. Select Create a restore point from the results.
  3. In the System Properties window, click System Restore.
  4. Follow the wizard to choose a restore point dated before the error began.
  5. Start the restore process and wait for it to complete.
  6. Your PC will restart and hopefully fix the error.
