Ouch. Well for starters, those should all be in "My Library", not "My Daz Connect Library", that one is for content downloaded by Connect.

The other problem is that you left all the content you are trying to install under the original unzipped folder names. If you look under each of those you will probably see subdirectories called "data", "people", "props" and one called "runtime". You aren't seeing "runtime" under "My DAZ connect Library" since it is a leftover from Poser. Many vendors still stick there textures under there. Any case, all these "data" folders need to be in the base level of "My Library" to work properly.

I'd suggest moving all the folders under TruForm, etc down one level, and put them in My Library.

Note: You will still only be able to find them in the content manager, not under smart content because they probably did not come with metadata information for the database to make them smartcontent.
