Welcome to HP Support Community, @Sa37-09_25 

Thank you for posting your query, I will be glad to help you.

If you see a “side-by-side configuration is incorrect” error when running the HP MFP Scan software for your HP LaserJet Pro MFP M438nda printer, follow these steps:

1. Check Event Log for Details

• Press Windows + X and select Event Viewer.
• Navigate to Windows Logs > Application.
• Look for errors related to the HP scan software to identify which component is causing the issue.

2. Use the sxstrace.exe Tool

• Open Command Prompt as an administrator:
• Press Windows + X, select Windows Terminal (Admin) or Command Prompt (Admin).
• Start logging with the command:

sxstrace.exe Trace -logfile:sxstrace.etl

Run the HP MFP Scan software to reproduce the error.

• Stop the trace and parse the log:

sxstrace.exe Parse -logfile:sxstrace.etl -outfile:sxstrace.txt

Open sxstrace.txt to identify the missing or corrupted component.

3. Reinstall Microsoft Visual C++ Redistributable Packages

• The error is often caused by missing or corrupted C++ Redistributable files.
• Go to the Microsoft Visual C++ Redistributable download page
• Download and install the appropriate packages for both x86 and x64 systems based on the error details.
• Restart your computer.

4. Reinstall the HP MFP Scan Software

• Uninstall the existing software:
• Go to Settings > Apps > Installed Apps, find HP MFP Scan, and uninstall it.
• Download the latest version from the HP Support site

Install the software again and check if it runs successfully.

5. Check for System Updates

• Ensure Windows 11 is up to date:
• Go to Settings > Windows Update.
• Install any pending updates and restart your PC.

I hope this helps.

Take care and have a good day.
