The La Femme in the package is an Education version (with no genitals) and will not affect your current installation of La Femme. There's a lot of content in the Premium Content folders which will work on both versions - hair, clothes, shoes, props, etc.

The HW figure folders are individual to those figures so you can pick and choose what to download. I would install the DawnSE folder to a temporary runtime in case some of the accessories included are not in your runtime.

None of the other files will affect your current installed figures at all.
