Can the Excel Viewer read .xls files

[Whiteowl047]

I recently dowloaded the lates Excel Viewer thinking I would be able to at
least read and .xls file sent to me. But when I try to do so, I get a
message that the viewer can't open that type of file. So am wondering if
there is something wrong with the Viewer I download or if the view simply
can't open an .xls file.

.xls is an excel doc so its not the file unless its corrupt
