Thanks for the suggestion. I tried both (either checked or unchecked)
but the problem still remains. More thoughts?
I can double click open an .xls or .xlsx file. I just can't define my
own association. (e.g. extension 'abc').

What kind of file is the .abc file? A real Excel workbook? Or a CSV or
TAB-delimited or fixed-width text file?
How did you do that with previous versions of Excel or with Word 2007?
Whatever that method was, doesn't it work with Excel 2007?

Try this from a command console:
ASSOC .abc=Excel.Sheet
then double-click it in Explorer.
Works here with Excel 11 (aka 2003).

interesting! Assoc works fine!
I tried to use Explorer -> Tools -> Options -> File Types to associate
file types with Excel but it doesn't work. The command line ASSOC
achieved my requirement.
.abc is either a plain text file or a tab seperated file.
