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.

I suspect it might be a 64 bit issue? I have the same issue. I also have Power Query installed.

Please help, otherwise I will need to install Excel 2010 32 bit edition... :(
