Office Project Type

Total Beginner question for all of you.

I want to redesign the appointment form to add a couple of checkboxes and things like that. I have Visual Studio 2005 Pro, .Net Framework 2.0, VSTO 2005, and the Full version of Office 2003 Pro installed on my machine (just for kicks, I installed the Office PIA redist as well).

When I try to open a Project Type of Office, I do not get that option in the directory tree. I can not figure out why I can not create an office project. I have downloaded some sample projects and I get an error "This project type is not supported in your installation".

Can anyone give me some guidance

Thanks!
