When you unpack Victoria, you're prompted for a location to save her to. This should always be the parent folder of a runtime. Once you get a lot of content, you'll likely want multiple runtimes, but for now I'm guessing you only have the runtime that got created with your Poser 8 install. Do you know where that runtime is on your hard drive? (When installing P8, you're also given runtime location options, so this isn't a given.)

In my case, I chose to install my P8 runtime to My Documents (I'm on XP Pro). So my P8 runtime is here:

C:Documents and SettingsUsernameMy DocumentsPoser 8 Contentruntime

So I would intall V4 to:

C:Documents and SettingsUsernameMy DocumentsPoser 8 Content

... and she'll wind up in the runtime.

Bottom line is that when installing V4 (or any other relatively recent properly formed Poser content - some really old stuff has to be dealt with manually) and prompted for a location to install to, browse to the folder that contains your runtime.
