This download will install all the files of the Nooalf V2 CD from 2003. MicroSoft has made changes to XP since then that reject all the fonts except 2NQ4YQ. All the fonts work on Windows 98, original versions of XP and will probably work on Millenium and 2000. The rest of the software is just pictures and sound files in a web style format, so will probably run on most operating systems including Macs with PC adaptor.
