Hi Rich,
>None that I know about. It was installed by hardware support group and I strongly doubt that there is anything other than standard installation. How could I check on this??
That would be under Tools > Add-Ins...

What I noticed is that you do not have the latest version of Excel 2003 installed. The latest version is SP 3. Additionally, I would re-install the converter for Office 2007 files after installing the service pack. So,
Service pack 3 first:

then the compatibility pack again:

>I suppose it's possible. The file extension, though, is XLSM. Is there any way to examine the file to see if that's not the correct format?
XLSM and XLSX are different files. XLSM does include support for macros. The person who is sending you the file would need to send you an XLSX file instead of the XLSM file.
