It seems that some of the Office 2003 interfaces changed
(Excel's theWorkbooks.Open in particular). I am using this
call in my Windows Forms application. Do I have to add
references to two Excel assemblies (2003 and prior) and
have to seperate 'Open' calls in the 'If' statement
(depending on the Office version installed on the client

In theory, the interfaces from Excel 10 (XP) should be forward-compatible
with Excel 2003. If your assembly references (only) the Excel 10 PIA, it
should work with Excel 2003. (If the new parameter is optional, hopefully
it will just ignored.)

Try developing a dummy test project for Excel XP, and then deploying it to a
different test machine that uses Excel 2003.
