Upgrading Internet Explorer
If you have installed the font and it is still not displaying properly this might be because you have an old version of Internet Explorer, if you are using a version older than version 5.5 then you will need to update it. To find out which version you are using, on your browser select Help, About Internet Explorer.
The easiest way to upgrade is to use the Windows Update icon in your start menu. Alternatively you could go straight to the Microsoft Internet Explorer Downloads website.
