cannot find matlab function wizard add-in in excel

I am not able to find the matlab function wizard excel add in on my C drive. I have followed the directions in the link below but still no luck: http://www.mathworks.com/help/releases/R2016a/compiler/excel/executing-functions-and-creating-macros-using-the-function-wizard.html

I am stuck on this step: 6. Browse to matlabroot/toolbox/matlabxl/matlabxl/arch, and select FunctionWizard2007.xlam. Click OK

When the browse window pops up I enter C:\Users\username\AppData\Roaming\Microsoft\AddIns\matlabroot/toolbox/matlabxl/matlabxl/arch but get nothing...

Can someone help?

Thanks
