Why is my PowerPoint presentation showing a missing font error?

1. Check the installed fonts on your device.
2. Check the document’s font setting to make sure it is set to the correct font.
3. If the font is not installed, download and install the font.
4. Verify if the font is a Windows system font or a third party font. Some third-party fonts may not be compatible with PowerPoint.
5. Verify that the font is not corrupted or disabled. Try to run the font file if available.
6. If the font is stored on a network, make sure the server is accessible and that the fonts have not been moved.
7. If the font is a third-party font, contact the font manufacturer and verify that the font is compatible with PowerPoint.
