That will leave you with the Outlook/Office 2007 PIAs installed, not 2003.
You will need a development machine or virtual machine with Office 2003
actually installed to do what you want.

Hi

I need to develop Outlook add-in in vs2008 to work with both OL2003 &
OL2007 on a PC with Outlook 2007. I have been recommended the following
method. Is this OK?

1.Install Office 2003
2.Install Office 2003 PIA (we need 1. to install 2003 PIA)
3.Uninstall Office 2003
4.Install Office 2007

Thanks

Regards
