In my experience with the sims, FilerView doesn't work right out of the box. The sim distribution does not contain all of the support files to run it.
Therefore, what I end up doing is downloading the regular ONTAP distribution from the NOW site for the release I'm running on my sim. Then I install it as I woudl on real filer (I usually have to increase the size of my root volume). Then I reboot my sim (no 'download' needed). This usually works.
You dont need HTTP to be licensed to access filerview, you need set the "options httpd.admin.enable on" registry. If registry enable doesnt work then re-install simulator. Give a try to Adam's suggestion too.
