HOW TO INSTALL:
After downloading and unzipping, put it in your xlstart folder which will load it when you start Excel. The folder location is different for each version of Excel, but is generally somewhere under:
C:\Program Files (x86)\Microsoft Office\ [version] \xlstart
or
For Office 365 subscription the xlstart folder is generally here:
C:\Program Files (x86)\Microsoft Office\root\Office16\xlstart
ALTERNATIVELY:
After unzipping, boot Excel and choose [ File -> Options -> Add-ins -> Go ] to manage Excel add-ins, then browse to the file you downloaded from here. People have had problems having it load each time when using the add-in UI, the xlstart folder seems more reliable.
