The download link includes music files to "mute" table music- place them in your Visual Pinball Music folder like it's laid out in the download.
Take the viper.zip file that you downloaded and extract to pinupsystem\puvideos folder as you would any other puppack. Select 1 of the 6 options that fits your system, try them all and see what you like if you aren't sure!
This will only work with version 1.1 PuP of Phenom's table.
This is for Fun DO NOT SELL or Redistribute.
