Running Excel 12.0 Application on Office 2003

After literally 30 hours of internet search I am asking for help....

I have developed an application in VS2005 + Excel 12.0 (Office 2007). Now,
I learn that some of the client machines will have Excel 11.0 (Office 2003)
and my application will not work.

I have read all about PIAs (2003 and 2007). It seems that If I develop the
application using 11.0, it will work with 12.0. However, how do I do that?
I cannot going to uninstall Office 2007 and install Office 2003 on my
development machine. If I install PIA 2003 on my development machine, I can
reference "Microsoft Office 11.0 Object Library", but not the excel
Libraries. Microsoft.Office.Interop.Excel still references "Microsoft Excel
12.0 Object Library".

The closest I got to was in this thread :

Does anyone have any known and proven solutions?

Thanks in advance.

Hello:
This is not really an answer to your question, but in my Consulting
practice, I found it useful to have several platforms. I have one system
with Office 2003 and another one with Office 2007 (I even have an older
system with Office 2000). I use Windows Home Server to share Spreadsheets
and Access Databases, and I use a terminal switch to move between
workstations sharing one monitor. It makes my life a lot easier.

I'm sure that you will get an MVP to assist you with your issue.
Kindest Regards,

The basic problem is that you can develop and build for the latest
version of Excel installed on the machine. For example, if you have
both 2003 and 2007 on the same machine, you cannot develop for 2003,
only 2007. This MAJOR flaw in VSTO was fixed in VS2008 and VS2010.

If you are writing commercial quality applications for Office using
the NET framework, I would strongly recommend Add-In Express For NET,
www.add-in-express.com . Their software makes it simple to write NET
code for any version of Office going back to 2000 and provides
version-neutral interops so you're not tied to any particular version.
Nearly all my commercial work is based on AIX templates.

Cordially,
