As a new member, let me say that I'm happy for participating to the DAZ|Studio-Renderosity Forum! My avatar is, for the moment, one of my oil paintings because it will take a long time before producing something as beautiful as what I'm seeing here!
I have Windows XP and DAZ|Studio 1.8, Victoria 3 SAE, starting to learning.

I just acquired and downloaded V3 Head Morph Pack and V3 **Body Morph Pack.
**The difficulty I'm meeting (getting nearly madman...) is the following:

whilst the archive ps_mr017-V3Heads (that with a red "Z") installs normally in the DazStudio "content" folder, I have problems with the installation of the .sit archive ps_mr017-V3Heads (that with blue SIT letters).

Clicking on it, the Stuff-It program opens; after extraction to a different folder, I obtain the archive "V3Head Morphs Install" that, according to my opinion, should be installed in the DAZ "content" folder too.
But, clicking on it, I'm asked with which program do I want to open it, with no possibility of installation.
Please tell me in detail what I have to do!
Many thanks and best regards,

Eduardo
