Is there a way to install Canary Excel Add-in manually from one machine to another?

This is possible however the machine will still need the .NET Framework 4.7.1. If that is already there, here are the steps to place the CanaryLabs-packedxll file on the machine:

• First, there is a 32 and 64-bit version of Excel. Check to make sure the excel version is the same on both machines. These can be found in:  Program Files(x86)\Canary Labs\Client Applications. They will not need to reside in the same location on the new machine. 
• Once they are placed on the machine, browse for them using Excel. The html document (which is the help file for the add-in) will also need placed in the same directory as the xll file. To browse in excel click File\Options\Add-Ins then click on the "Go" button.  
• Next, the user will need to set up the endpoint to the Historian. This will create a config file that will reside in the same directory as the xll file.
