How can I fix Runtime error 52: Bad filename or number?

  • Uninstalling apps clashing in the background might prove effective in handling this error. Also, a program called Worldox found in Excel, locate and delete it, then restart your program.
1. Reinstall runtime libraries
  1. Click on the Windows icon and open Settings.
  2. Now click on Apps, next on Apps & Features.
  3. Find and highlight the Microsoft Visual C++ Redistributable Package, now click Uninstall at the top of the list.
  4. The moment you are done, restart your computer.
  5. Lastly, download the latest redistributable package from Microsoft, then install it.
2. Perform in-place upgrade
  1. On your favorite browser, go to the Windows 11 Download page.
  2. Click on Select Download under Download Windows 11 Disk Image (ISO), then choose Windows 11.
  3. Next, click the Download button.
  4. Choose the product language you want, then click the Confirm button.
  5. Now you will receive a download link, and you will be able to click on the 64-bit Download button to get the Windows 11 ISO.
  6. Right-click the ISO file you downloaded and select the Mount option. Another option for this is to create a bootable USB or DVD.
  7. A new virtual drive will pop up in your File Manager window. Click on it and double-click the setup file to begin the installation process.
