While using Install Manager or Daz Central can certainly make life simpler you can download zips from the Product Library pages in your account. They are still set up for one of the installers, you need to take the files out of the Content folder in the zip and merge them with your regular Poser Runtime. For Victoria 4 don't forget to run the /Runtime/Libraries/!DAZ/DzCreateExPFiles-v4 command for your operating system after installing the morphs and base figure.
