1) First download all these files into a temporary directory. Let's say you call it: "C:\TEMP":

file1

file2

file3

2) Then go into your FONT directory (often called C:\WINDOWS\FONTS)

3) In the menu, click on "Install new fonts"

4) Tell the computer where to find the fonts (C:\TEMP). Don't forget to tick the box: "Copy these fonts into my FONTS directory".

5) Delete your temporary directory. You don't need it any longer.

That's all!

NOTE:

Using this font is quite difficult, because you need to go into the menu "Insert special character" each time you need to insert an IPA symbol! Don't bother with it! Set up shortcurts to these symbols.
