Sorry. Install from Zip does NOT work with DAZ as I said above. DAZ files are Zips but they contain, as I said above, an additional 'Content' folder that results in not being able to even see the content in Poser unless you manually move the subfolders. For DAZ files, use your File Manager to manually unzip and move folders to your Runtime from any DAZ purchase. For anything else, it works perfectly, as long as you have at least one Runtime to install to, To learn how to have Runtimes or what they are and how the files are structured under them, please read the manual that comes with the software. If you ask how to add a runtime to your library, also please find it in the manual. I am at work computer so can't copy and paste right now from the manual directly but maybe someone else is in the position to do so.
