Word file will not open (Is it a corrupt file?)

We have a folder on the server with some word files that now cannot be opened by anyone. The error we get is windows cannot start the converter mswrd632. I tried the fix listed in microsoft knowledge base 973904 but that seems more for if the problem was happening for every file and not just these few and we can open and edit other word files. Is there some way perhaps these files were saved incorrectly or something? I have attached one that will not open to see if anyone else can open it and tell me what we cannot.
