Microsoft Word (inside your copy of Office) is supposed to be able to open Word Perfect documents if I recall correctly. Try changing the filetype options in the open dialog if it doesn't use a Word Perfect specific file extention (.wpd if I recall,) and is the old .doc extention which Word might assume is a MS Word file.
Thanks Nazo
renamed file from .wpd to .doc
Then when I tried to open it winoff wanted to download the converter from disk , I obayed and poof I can now read wpd docs
