Daz Studio 3 is considered by some ppl as “dead” software.I still have somewhere rared (archived) on my computer Daz 3.1.2.19 and Daz 3.1.2.24.If an admin can confirm if it is ok to create a sharing post for you then ill try to help you, but why can’t you just copy your setup installer and give it to her and she’ll write to daz for a serial request..if you still have the setup 
Adamr001 said “Only difference between 3.1.2.19 and 3.1.2.24 is the Bryce Bridge… I’ve had no slowdown issues on my machine when comparing the two.” but anyways daz 3 is buggy with the content manager and youll need to run a backup data content script when you install new content and rename a folder , red my replies here :

Personally i have the daz 4 free version but without content, im thinking to reinstall daz 3 becuse many of the great addons such uberenvironments,uberlights, or reality 1.5..are compatible with daz 3 only and i have old content compatible with 3.If daz keeps releasing new versions and the purchased “addons” are not compatible any more every month i might uninstall everything and move to 3ds max or maya ..or free org software such as blender.So far i enjoy Bryce more than daz lol 
Oh and here is a post about the photoshop bridge to daz3
