I have a VB.Net application that contains controls (spreadsheet and
chart) from the OWC.dll version 9. The application runs fine with
Office XP, but fails to run when the PC has Office 2003. Although it
does run with Office 2003 if Visual Studio.net is installed. I've
researched this a lot but I can't seem to find out first why the app is
failing/not failing and two, how to fix it. I think it may have
something to do with the way that Office 2003 installs the OWC11 PIAs.
It appears that dao.dll and mscomctl.dll aren't given full trust when
they are installed. I'm not even sure why this would matter as the
components I have in the application directory are from v9 of OWC.dll,
so they should be the ones being referenced.

Anyone have an idea on what to do to get the app to work with Office
2003 when VS.net is not installed?
