Can you post the original install file for the Hexenworld client? The readme says to install it before installing Hammer of Thyrion, but I can't find a copy anywhere. The links at Raven-Games.com are broken, but it looks like "hwclient_beta_15.zip" is the file I'm looking for.
gamers.org mirrors those files. For hexenworld, see here:
Ah, okay, great! I googled and googled looking for that file. Gamers.org never came up. Thanks for the link! Out of curiosity, why not just post the hexenworld files and official patch on the thyrion website?
Well, because we actually ship all required hexenworld files with our hexenworld packages: if there is a previous installation of it, our packages will overwrite them; so we don't bother. However, windows users are more comfortable will 'installations' and menu entries and the original hexenworld installer does that, hence the presence of that note in the windows readme file.
