CW is notorious for wanting one to hew precisely to the installation prerequisites. For that and other reasons, I have been leaning towards using the soft appliance version of the software for new installs. You simply drop the ova file into your vCenter server and it hands you a successfully installed VM ready to discover your network.
I'd also adivise that you consider bringing the installation up to the current (4.2.2) version. If it's a greenfield installation, one might even consider starting out with the about-to-be-released Prime Infrastructure 1.2; which finally merges LMS and NCS.
