Hi Jack,
we ran into the same scenario with msl 9.x, we installed the msl and could not install all the blades from the cd, we literally had to license the msl software and log into the console and install the blades from there.
there is a tab that says BLADES.
just be sure of the configuration of all IP addresses and FQDN on installation as there are known issues with changing this after the initial setup.
Hope this helps
