title: Icons8 Lunacy says: "Missing Fonts" even though they are installed on my PC?
body: <p>I was given a sketch file, and since I have Windows, I installed Icons8 Lunacy to read that file, but when I try to open the file, I get a message saying that a font called (Avenir-Heavy) is missing even though I installed it on my PC for the third time and I can see on my Fonts settings that it's there, some fonts were missing also in the start but managed to install them and they were removed from the "missing fonts" error message, yet (Avenir-Heavy) is stuck there, I don't know why ?!</p>
  
  <p>Can somebody help me fix this please
  Thanks in advance</p>
