Microsoft Works is a collection of programs which includes a word processor.
Unfortunately it is not the same as Microsoft Word which uses a different format so few people will be able to open his Works document.
See if he can create it as a pdf file.
It is very easy to convert a Word document to a pdf file so converting a Works document may be no more difficult.
There are plenty of free programs that can create pdf files, like this one called pdf995 (there are others)
