Solution 2 – Reinstall the font

If you have upgraded to Windows 10 from Windows 7 or Windows 8, it might happen that your font wasn’t installed properly so you need to reinstall it manually.

If this sounds complicated, don’t worry, it’s actually simpler than it sounds. To do this, simply do this:

  1. Go to C:\Windows\Fonts if you did a clean install of Windows 10. If you have upgraded from Windows 7 or Windows 8 you need to go to C:\Windows.old\Windows\Fonts.
  2. Now you need to find the font that is giving you trouble. In most cases, it’s Arial or Mingliu. Find the font file and open it to preview the font.

You can also install the missing font using the Command Prompt. This method is intended for advanced users, but it’s also faster than the previous method. To install the missing font, just do the following:

  1. Press Windows Key + X to open Win + X menu. Now select Command Prompt (Admin) from the list. If the Command Prompt isn’t available, you can also use PowerShell (Admin).
  2. When Command Prompt opens, enter C:\Windows\Fonts\Arial.ttf and press Enter.
