Commented Unassigned: Excel doesn't show NodeXL [25669]

I've installed it and run Office 2013 (64bit). I am not seeing the tab that should be there. I have uninstalled and reinstalled several times - but, I do not see how to start nodexl.

I downloaded the NodeXLExcelTemplate2014Setup.exe file, ran it and it installed successfully. I open Excel and I see no difference.

Ouch!
that's soooo painful.

and at 7 minutes into the video it's not at all obvious - ah well RTFM i guess.
