Where to put folder level script for saving function on a common drive

Hello i'm developing a pdf where the save button will choose for the user the folder and file name. I Know to do this from Try67 tutorials that I will need to put a folder level script. My question is if everything is done in the common drive environment, H drive (all users have access) but programs are not install there but in the local C drive. Where would i put the folder level script to make sure everyone will be able to have the button working when using adobe reader.
