Can Not Find Add-In Mscoree.dll

[GordonC]

I am trying to create an Automation Add-in for Excel using C#. I have tried
to following the directions in the MSDN article
http://msdn2.microsoft.com/en-us/library/ms173189(vs.80).aspx

I have Visual Studio .NET 2005 Standard and Office 2003. I do not have
VSTO 2005. I do have VSTO 2003, but it is not installed. The MSDN article
ms173189(vs.80) does not specify a requirement for VSTO.

I am implementing the exact same tax calculation example appearing in the
MSDN article.

The article specifies the creation of a class library project. I chose the
Extensibility > Shared Add-in template. The resulting project does install
the add-in.

However, in Excel when I click on Tools>Add-Ins and select
ExcelAddIn.Connect, I get the message that Excel can not find the Add-In
mscoree.dll. I am the administrator for the computer.

Do I have to create a Shim for mscoree.dll? I understand this is not
required on the development computer. Is there some other problem?

I will appreciate any suggestions.

I can not just ignore the lack of a mscoree.dll warning. Excel removes the
check mark by the Add-In to note that it is not loaded. A cell in a
worksheet using the function generates a #NAME? value.
