IMPORTANT-Windows-Excel-Info.txt

In July 2016 Microsoft released a security update which may affect downloaded XLA and XLAM add-in files with Windows Excel. 

After you load the add-in XLAM file, if the menu item does not appear in the Add-Ins ribbon and the add-in does not respond to the shortcut key, quit Excel. 

Use your file manager to navigate to the add-in XLAM file on your local drive. 

Right-click the XLAM file, and choose Properties > General. 

If there is an option to Unblock, click the checkbox and click OK. 

Then launch Excel, and use Excels File > Open to load the XLAM file, or follow the instructions for installation.
