For reasons history knows best, the support files for Roxie were still mixed up in the Poser 11 application support files. In fact there was a lot of stuff there one not really needs to run Poser.

These legacy support files are now provided as a zipped runtime archive.

You can either unzip this runtime and put it in your library search path, or you can pull the required files directly from the zip into a smaller dedicated runtime.

I have for example collected all Rex/Roxy stuff from the nudes, garments, etc. zips into a dedicated Rex/ Roxy lib together with the considerable stash I had for Roxy. I had same for non-native figures. Took a little time but it works great for me. Also a good occasion to clean up.
