The archive contains 2 files, which should be copied to C:\ProgramData\Philips\ProntoEdit Professional 2\Libraries\
Keep a backup of the original files, just in case. Edit the xmlrpc.js and change the ip address to the one of your own XMLRPC server.
Once you've done that, you can add the libraries to your Pronto project and have fun
