can't remember exactly which one it is, but it is for one of
the 2
reasons (or both of them):
1) your web server does not have the mime type defined for
this file type
2) your browser sends incorrect mime type data with the
upload
if you do have Office 2007 installed on the computer you are
uploading
from, but still see this error, then it is reason #1...
