Cisco Configuration Professional (CCP) 2.6 is a legacy GUI-based device management tool used primarily for configuring Cisco access routers. While newer web-based versions exist, version 2.6 is the specific PC-based "desktop" version required for many legacy labs and older Cisco IOS devices.  Key Features of CCP 2.6 

Admin Rights: You must run the executable with Administrator rights for proper installation and operation.
