I can see the Yammer MSI available now (link below).
Does anyone know where the supporting documentation for the MSI is? It behaves a bit differently to what I'm used to (in my limited experience). The MSI creates a Computer Wide Installer on the target machine, then through some mechanism installs to any user that logs on (I think).
