Detailed Results in xls format (tab delimited text)

The file type mentioned in this message is
Microsoft Office Excel 97-2003 Worksheet,


I think the clue lies in those 2 lines.
If the file is a tab delimited text file but has an xls extension it is not
surprising that you get the message:
The file you are trying to open, [Filename], is in a different format than
specified by the file extension.


I would think that you need to change the file extension used to be .txt or
.prn

(I am not expert in web page links so I can't help you to achieve that; you
could seek help in a forum that specialises in web page design).
