Unable to installer fonts on Windows 10

[ForumBot]

J'utilise Windows 10 x64 Pro and I'm unable to preview or install fonts.

Quand je try to preview a font (double click or `Right Click >> Preview`), I get an error message that reads "The requested file is not a valid font file" as shown in the screenshot below:

Quand je try to install a font (`Right Click >> Install`), another error that reads "The file does not appear to be a valid font" is shown (screenshot below):

Things I've checked:

- J'ai UAC enabled in my registry but set to lowest setting "Never Notify". I thought UAC had something to do with this, but the behavior is the same whether or not `EnableLUA` is set to 0 or 1 in registry.

- J'ai checked the Observateur d'événements (Application and System sections) for hints to the problem, but this error is not reported at all in the logs from what Je vois. This seems strange.

Pourquoi ne puis-je pas install fonts on Windows 10? I verified the behavior with several downloaded `otf` and `ttf` font files. So I'm fairly certain the files are not corrupted.

## EDIT

Quand je allez dans the Fonts section of Panneau de configuration, I do not see an "Install Font" option in the "File" menu, as shown in the screenshot below.

After a week of trying everything. **The answer as weird as it sounds is to enable the windows firewall.** *Je sais, makes no sense right?* It's not connected to font settings, however once "On" J'ai pu fix my issue with installing fonts on windows 10 and without an error message!
