Print screen it, run it through ABBYY FineReader, proofread it, export to HTML, import into Sigil, edit it like mad and take pride in the result.
If you're looking for an easy "one click" solution, there is none. Depending on the structure perhaps you could try with 7-Zip or WinRAR (by right clicking it - Open with WinRAR, 7-Zip). Meh... it probably won't work, especially if the author applied some form of encryption. But it's worth a shot. Personally I think print screening is still your best bet. It sure beats scanning, I'll tell you that!
