I had so much trouble trying to get NodeXL to install (either basic or pro). I kept receiving an error about Smrf.NodeXL.ExcelTemplate.vtso not being found (some error 8007007E, i think).
I finally solved this problem by installing the Visual Studio 2010 Tools for Office Runtime (link here: https://msdn.microsoft.com/en-us/library/ms178739.aspx). I have no idea why this was necessary, but it got things working.
