Excel and Works are two different programs, although you could save Excel
workbooks as *.wks files.

What are the file extensions of the files you are trying to open?

If actually *.wks you cannot open in Excel.

There is no patch.

If the files are 97 - 2003 *.xls Excel files they should open in 2007

Perhaps they are just corrupted?

cannot read .wks. I have been told there might be a patch, but could not
find it.

Your help would be appreciated!
