# Installation Installation is simple. All files are installed on the Server PC only, there is no need to install any files on any other PC. There is no need to setup a mapped network drive, as there was when installing Aastra 400 CCS v1, nor do you need to changed the advanced server settings, as you did with v1. Run the 'setup.exe' as Administrator and follow the instructions as you find them. Please note, the setup program will attempt to close any CCS programs that are still running. This is an automated process which usually works but we recommend that you manually shut down all CCS programs before installing to ensure there are no unforeseen problems,
