Hi rayguilliard,

There seems to be a bug in the Microsoft Visual Studio Tools for Office Runtime. Could you please try to move VSTOInstaller.exe.config in C:\Program Files (x86)\Common Files\Microsoft Shared\VSTO\10.0 or C:\Program Files\Common Files\Microsoft Shared\VSTO\10.0 away be renaming it to to VSTOInstaller.exe.config.old as suggested in this article and try to install the addin again?
