Some zip files will install to the proper sub-directory if you unzip them in your main Poser folder. Other zips will install if you unzip in your root C: directory (assuming poser is on C:). Some unzip to "Program Files/Meta Creations/Poser" while others to "Program Files/Curious Labs/Poser - all depending on how old the file is (the standards have changed over time but there are still a lot of old zips out there). Best thing to do is open the zip (to look at the contents - not unzip them) and determine the placement intended by the author for the final destination folders. Then unzip to a temp directory (without using folder option) and move the files manually to their proper destination folder. There are some "installer" utilities that attempt to do this themselves, but I find it just as easy to do manually. Except for main geometry files (.obj and corresponding .rsr files which must be placed in the exact sub-folder of /runtime/geometries that the author specified), all other files are more flexible, and can be in any sub-folder of their proper type (see list below) All files may or may not have an identically named .rsr file which always goes wherever the main file goes. All images (.jpg .bmp. tif, etc.) = /runtime/textures/[anyfolder] .cm2 (camera files) = /runtime/libraries/camera/[anyfolder] .cr2 (character files) = /runtime/libraries/character/[anyfolder] .fc2 (face files) = /runtime/libraries/face/[anyfolder] .hr2 (hair files) = /runtime/libraries/hair/[anyfolder] .hd2 (hand files) = /runtime/libraries/hand/[anyfolder] .lt2 (lighting) = /runtime/libraries/light/[anyfolder] .pz2 (poses) = /runtime/libraries/pose/[anyfolder] .pp2 (props) = /runtime/libraries/props/[anyfolder] in addition, files created with the ProPack will have .png files instead of .rsr. files. Both .png and .rsr files get placed wherever their identically named counterpart is placed. Sounds complex, but it isn't. You will have it memorized after your first few tries at it. You might even place a shortcut on your desktop to your /Poser/Runtime folder - because you will be going there a LOT! Hope this helps, Ronstuff
