You open it in Visual Studio, link it to the Office 2003 instead of 2007 PIAs,
and test to make sure your code doesn't contain anything that's not available
in the earlier version. Pay special attention to method signatures, as the
Office object models are VB-based and tend to accumulate additional optional
parameters in newer versions.
Quite often, you can put an app developed against an earlier version on a
machine with a newer version and it will run. But it's very chancy with C#,
due to those method signatures.
MSFT "best practice" is to develop/distribute a separate application for each
version of Office, thoroughly tested against that version.
