Alternatively, PI can be installed manually using wxLauncher and the download links below. Create a folder called PI in your Freespace 2 directory and extract PImain.vp, mod.ini and PI.bmp into it. PI is designed to work with the Media VP asset upgrades, and PIassets.vp should be extracted into the PI folder too if these are installed. Start wxLauncher, select the PI directory as a mod and start the game.
