Simply go into the CDRom, Documentation folder, and the Copy These 2 Files folder. Highlight both files with Ctrl-A, copy them with Ctrl-C, and go into your VST Plugins folder of your recording software (typically C:\Program Files\Company Name\Product\VST Plugins) and press Ctrl-V to paste the files into the directory. When you launch your application, the plugins should show up.

The files you need to copy are: PS03-Drums&Percs.dat and PS03-Drums&Percs.dll

example: CubaseSX would be C:\Program Files\Steinberg\CubaseSX\VST Plugins\

Logic would be C:\Program Files\Emagic\Logic5\VST Plugins
