One of my developers was trying to create a toolbar button which automatically setup some text styles/parameters. Everything was fine except that on some machines, the button would fail – the error was “Font file doesn’t exist”. He was using a very commonly used font file “arial.ttf”, indeed arial.ttf is the default font for the “Standard” AutoCAD style.
It seems there are very important updates the Font packs that you need to include (update) with your Windows installation – check out https://www.microsoft.com/typography/fonts/
I’m guessing Windows update also includes these Font updates as ‘Optional’ – best install them for an easy life!
