If you want external Runtimes for Poser 5: 1.) Create a folder with the name of the Runtime (Mike3, for example.) You can use a good file manager program. 2.) Install something directly into the new Runtime folder (ex: Mike 3.)If you use a DAZ instaler, it will go into it just fine. 3.) You might want to use CorrectReference (CR Free), or better yet CorrectReference Pro (CRPro, available in Marketplace.) You're set.
