Philywebrider, have a look at the help file (P3dOExplorer.chm). Double-click on it from the zip and read the "getting started" section. You will see the above picture and the explanation on how to unzip all stuff. The picture in itself is helpfull. All .DLLs should go in same folder as P3dO exe. Now if you know Winzip enough - and if you use it - there's an option to unzip files with the same folder hierarchy as the zip file have. Use this option and the zip will self-install P3dO effortless. There's a picture with this option checked on the help file "getting started" page. is this ok ? 1.5.4 will now have a setup, sorry for inconvenience.
