When you say Options, do you mean under the Wiki admin menu option, or through Add-ons > VaultWiki > Options?
I'm currently not able to load any of the wiki-related pages within the Wiki admin menu, since they all return the message "The wiki is currently being upgraded. Please check back later." I can alter Addon settings for VaultWiki just fine, though.
I'm now wondering whether something was left behind from b001 (particularly with the install hiccups prior to fixing), which I uninstalled before copying b002 files then (re)installing from step 1. So I might try dropping my xf2 testing database and bring in a backup from before b001, then install b002 and see if I'm any better off.
