File is at Retrieve

unzip it and there is a folder inside called Thai fonts

Win XP/Vista:
Go to 'Control Panel/Fonts'

Click 'File/Install new font'

Go to where you unzipped it and highlight them all and press enter


If I remember right it prompts you a couple of times because the same fonts are in Windows so it's up to you if you want the new one or the old standard one.

I always just click OK and never had problems
