I'm not sure exactly what you've done so far, but when I'm installing new
fonts this is what I do:
[1] Open up the Start Menu
[2] Click on Control Panel
[3] Open the folder marked Fonts
[4] Place the new fonts in the folder or extract them into it.
[5] If you want to you can refresh or Restart the company to make sure the
fonts take effect. Thats what I always do after changing any new settings.

Hope this helps...
