The DIM actually installs security stuff for DAZ into the depths of your computer. Once installed, the DIM cannot change it. So, when I tried long ago to route purchased content to my preferred library, it could not do that (a legitimate bug), but then could not change it to DAZ's default. Since then, I am locked out of Daz studio, due to the way the content manager works, all because of this old "security" bug.  Bah. I just go with other vendors.
