I've downloaded a few TTF files from the web... -I tried dragging the files into the Windows Fonts folder and they won't go. -I tried copying the files but the paste option is greyed out. -I tried opening the files hoping for an "install" option and found nothing. -I tried looking at the font properties for an "Unblock" button and there isn't a block on any of the fonts. Others who have downloaded from the same website say they've had no issues. Any thoughts?
