Where the microsoft.office.tools.excel.dll is installed?

I have installed VS2010 SP1开发者_开发百科 with .NET 4.0 and cannot find where the microsoft.office.tools.excel.dll is located.

Question> Where I can find this DLL?

Normally this assembly should be in the GAC once you install the Office Primary Interop Assemblies assemblies. On my computer the assembly is located in:

c:\Program Files\Reference Assemblies\Microsoft\VSTO40\v4.0.Framework\

And here's the corresponding article on MSDN about installing those assemblies.
