If you've got a zip file, open the "content" folder in the zip file, then extract the folder called "runtime" and put that where you want to put Vicky.

If you've already extracted the "content" folder, just move the "runtime" folder that's inside the "content" folder to where you want it.

Then you have to run the .bat file to initialize her morphs, but we'll worry about that after you get her installed.

Also, make sure you downloaded the right file. There are three versions. For Poser, you want the file called IM00004783-01_Victoria42Base.zip.
