Richard,

We had similar issues with Word, and the problem was solved by compiling/building with the lowest common denominator, in our case Word 2000. However, there is a problem building an app on a machine that has more than one version of Word ... I think it automatically builds with the latest version anyway (which is probably what you're running into with Excel).

But I didn't actually know how different (if at all) it might be for Excel ... so I Googled "Excel versions for COM Interop" and found a good link that might solve your problem:

>We have multiple versions of Excel (97-2007) installed for various users. I have 97 and 2003 installed on my development machine. When I deploy the application, users with Excel 97 get a COMException. Is there any way to get VS2005 to go with the Excel 97 for the purposes of Interop? When I referenced Excel I made sure to reference the Excel 8.0 library. Any ideas?
