Can you open an Excel file by double clicking on it in Windows Explorer?

>It works OK for text files and most word documents but not for excel.
>When I try to run an excel file i get the message " DDE error has occurred, and a description of the error cannot be displayed because its too long. If the filneme or path is long, try renaming the file or copying it to a different folder."
