Preview – Open Sans is not displayed

I just started my first prototyp with Axure 9.
I used the Font Open Sans in my design. This font is installed on my computer.
At first everything works fine. But when I added the font in the Share-HTML-Font Settings, like I always did with Axure 8, it does not work. Even in the Preview the Open Sans is no longer used. I deleted all my font settings, but it stayed the same.

In the HTML I can see, that there is no font defined…


Things I already tried:

  • · Delete all the Font Settings in Axure
  • · Re-Start the program
  • · Re-Start the computer
  • · Deactivate the Open Sans on my Computer
