Excel 2003
 

I had a macro that was working yesterday. Last night my
computer got upgraded to Excel 2003. The macro errors out
on the following line of code:

Set ExcelApp = CreateObject("Excel.Application")
ExcelApp.Visible = True

The error I'm getting says something "not supported by
object library"

The object library is Excel 11.0.

Any suggestions would be great. Thanks.
