With that said, a word of caution about zip installation.  It is best to either open the compressed file with winzip or unzip into a dummy runtime in order to examine the folder hierarchy within.  Many vendors usually adhere to the proper way to package a product.  However, freebie content may contain an additional folder where the runtime is nested into it.  Not very prudent when you start to hunt for it in your Poser library.  Also, many users will advise against bloating your app runtime with too many characters and content.  Best to start organizing and creating specific runtime folders for easy access and identification.
