Hi HomerJ,
Unfortunately there is no way for this to happen at this time, I did more research with some senior engineers to validate if there is a workaround or something that can help us to get the Microsoft Excel and Word add-ins installed without having to run the wizard or have end user intervention, however at this moment, such Is not possible, due the following reasons:
* The add-in is packaged currently as an ''.exe''
* If it were an ''msi'' this would then be possible
* If it were an old Add-in version , it could be possible as those were based on VBA
* New add-in versions are based with the Office architecture and thus not possible
I hope this helps answer your question unfortunately what you are wanting to accomplish is not possible due to the architecture in place currently.
