When installed on Windows 7 (x86) using a system account (Like via SMS or SCCM) the install will not work. In this scenareo the MSI package installs the applicaiton to "C:\Windows\System32\config\systemprofile\appdata\Local\Microsoft\Office Labs\Ribbon Hero"
This package will not function corretly if silently installed with local system account as the start menu shortcut is pointing to the users profile and not the system profile.
However if the install is done using the user account then it does install without needing any elevation of priveleges as it is a stand alone app and addin to Office.
BUT... The installer is also a "Per User" install and does not install to the default user account of the PC so all users of a PC must install the application.
If using SMS or SCCM to deploy it the program can be run using the "Run once for every user who logs on" option on the program.
