==Installation==
The client is normally distributed with an executable installer and profile file(s), which contain all the necessary information to easily connect to a network.
==Availability and compatibility == ▼A .pcf (or [[profile configuration file]]) is used to configure the VPN client for connecting to the remote server.
The software is not free but is often installed on university and business computers in accordance with a site-license. As with most corporate licenses, administrators are allowed to freely distribute the software to users within their network.
The open-source [https://www.unix-ag.uni-kl.de/~massar/vpnc/ vpnc client] can connect to most VPNs supported by the official client.
==Compatibility==
VPN Client 4.9.01.0230 beta added support for Mac OS X 10.6.<ref>[httphttps://www.cisco.com/web/software/282364316/35919/4.9.1.0230-beta-rel-notes.txt Release Notes for VPN Client, Release 4.9.01.0230 Beta for Mac OS X]</ref> Stable version 4.9.01.0180 appears to lack that support; 4.9.00.0050 explicitly did ''not'' support versions of Mac OS X later than 10.5.<ref>[httphttps://www.cisco.com/en/US/docs/security/vpn_client/cisco_vpn_client/vpn_client49/release/notes/49client.pdf Release Notes for VPN Client, Release 4.9.00.0050 for Mac OS X, Revised: May 21, 2010, OL-11179-04]</ref>
