"To summarize: if you install VSTO 2005 SE on top of a clean VS 2005 Professional, you won't have the document-level templates. If you want to have them you need to have VS 2005 Team Suite/Team Edition or you need to install the previous version of VSTO: VSTO 2005. So VS 2005 Professional + VSTO 2005 + VSTO 2005 SE will give you the document-level templates!"
So my question is, does anyone have a link to a VSTO 2005 download (it is no longer available from Microsoft).
Maybe this one will help Microsoft Visual Studio 2005 Tools for Office 2005 Runtime (VSTO 2005 RTM)
The VSTO 2005 redistributable package installs the Visual Studio Tools for Office runtime, which is required to run solutions built using VSTO 2005. This runtime supports document-level customizations for Microsoft Office Excel 2003 and Microsoft Office Word 2003, and application-level add-ins for Microsoft Office Outlook 2003.

As Richard said earlier in this thread, the "document-level" project templates (Excel Workbook, Excel Template, Word Document, and Word Template) are not included in VSTO 2005 SE or Visual Studio 2005 Professional. To get the "document-level" project templates in the 2005 release of Visual Studio, you must have one of the following versions of Visual Studio:
Visual Studio 2005 Tools for Office (this is a completely separate edition of Visual Studio for purchase; it is not a free download).
One of the "Team System" versions of Visual Studio 2005.
The VSTO development story is somewhat simpler in Visual Studio 2008. In this release, all of the VSTO projects (add-ins and the document-level projects) are now available in Visual Studio 2008 Professional, as well as the "Team System" versions. This includes add-in and document-level projects for both Office 2003 and the 2007 Microsoft Office system.
