not provided
Scenario
Editing or presenting a slide deck that contains custom or third-party fonts, specifically Arabic scripts.

Before you start

Before attempting to fix the issue, ensure you have the original font file downloaded and saved locally on your computer for potential reinstallation.

Solution 1Recommended

Verify and Reinstall the Custom Font

Check if the font is properly installed at the system level so PowerPoint can recognize and render it accurately.

Third-party fonts like FS Albert Arabic often encounter display issues if they are corrupted during installation or not installed for all users on the operating system.

1
Check current installation

Open the Windows Control Panel, navigate to 'Appearance and Personalization', and click on 'Fonts' to verify if your specific custom font is listed.

2
Reinstall for all users

If the font is missing or acting up, locate the downloaded .ttf or .otf font file, right-click it, and select 'Install for all users'.

3
Restart PowerPoint

Completely close Microsoft PowerPoint and reopen your presentation to force the software to refresh its font cache.

Verify and Reinstall the Custom Font
Check for Updates: You may also want to contact the original font provider to ensure you have the latest version of the font file, as older versions might lack modern application compatibility.

Frequently Asked Questions

Why do my custom fonts change when I open the presentation on another computer?

This happens because the custom font is installed on your original computer, but not on the second device. To fix this, you need to embed the font in your presentation. Go to File > Options > Save, and check 'Embed fonts in the file' before sharing it.

Are all third-party fonts fully compatible with PowerPoint?

No, some custom fonts, especially specialized ones like certain Arabic scripts, might not have the correct TrueType or OpenType tables required by PowerPoint. This can result in rendering issues or characters overlapping unexpectedly.

How can I tell if a font issue is caused by the file or the font itself?

The easiest way to isolate the issue is to apply a default system font (like Arial) to the affected text. If the standard font renders without any issues, the problem lies with the third-party font's compatibility.
