when this is a demo that requires MoldDesign then you have
to buy it at $$$$ it's not standrad in SE.
When you have a license for it then it can be reached via
Applications --> MoldTooling (menue entry is active then)
hard to say because I don't own it. Usually you install extras
from the DVD then add the approriate license string to your
license file and that's it.
BTW: MoldTooling is available only from within the assembly
environment.
