Business Reporter installation is successful, but not "active"

I would like some clarification for the process of installing the IFS Business Reporter add-in for Excel under Apps 10 (UPD20). Based on the “Add-ins” page, there are two options, the .MSI installer or the “Click-once” installer. Upon further investigation (technical documentation), there is also a “SETUP.EXE” that can be found in the “BUILD_HOME” delivery (under ...\build_home\win32client\IFS Business Reporter\Install). I am unable to get any of these to work properly (all exhibiting different symptoms). The most recent attempt was to run every installer that was linked on the “Add-ons” page (i.e. https://server:port/add-ons.html), and it seems to work, but still throws an error stating the the “upgrade utility not found”. Does anyone have any advice on how they use BR and how they installed the “add-on”?
