Hi,
AFAIK, VSTO 2003 was an add-on to be installed on top of some VS.NET 2003
edition. I haven´t found its download page.
On the contrary, VSTO 2005 is also a VS 2005 edition apart from the
Professional, Standard, etc. ones.
See:
Visual Studio 2005 Product Line Overview

Thank you, Carlos.
Yes I have not been able to find the download for VSTO 2003 either...I've
spent quite a bit of time searching also. I would really appreciate anyone
who might know where it may be obtained.
