If you have a previous installation of Inter, you should make sure to remove those fonts files before installing new ones. ClearType-hinted fonts Inter also comes with a version that has TrueType hints used by ClearType on Windows. This changes the appearance of the fonts when rendered on a system with ClearType enabled and can in some cases increase the legibility of text. However, the hints for Inter are automatically generated and are not always a good thing. If you do prefer to use the version with hints, use the font files in the folders with "hinted" in their name, like "Inter (TTF hinted)" See https://github.com/rsms/inter for more information
