There is no way to change the language in-game, and no official language patch. A couple people have had some success replacing certain files, though.
Here is a
download link (1MB) for some English files. It is in a self-extracting
7-Zip archive, so you can change the extension to .7z and open it with that program (other archive managers also support this format) if you don't want to run an executable.
See the following topics for details of previous attempts (with partial success);

If you are not comfortable with Registry editing, check out
