In recent days, I can't install fonts.
Here is my process:
-I downloaded the font selected on the site
-I found in his file
-I extract (I'm on Winrare)
-I open the file where there is all computer fonts
-I dragged police from one file to another
And at this stage a tab appears saying that "the police do not seem to be a valid font". So I try with other police, but it always makes me the same thing ...
I also add that since I made my computer updated some strange things happened, so it's possible that it was a link. I also want to say that I have already succeeded to record multiple fonts but before now I can't.
Do you have a suggestion?

Police,en anglais se dit 'font'.

Ton "I dragged police from one file to another" n'est pas transformé en un raccourci, par hasard ?
Copie-colle la police dans le dossier Fonts de win7.
