According to Cisco itself, the Cisco VPN Client is now obsolete and is no longer being developed or maintained by the company. This makes it unsafe for use and therefore not to be trusted. Cisco AnyConnect Mobile VPN Client is the application's successor and the tool to try in case you want to use a VPN client made by Cisco.
The Cisco developers provide users with the possibility to read about install and uninstall procedures using their Support page. I recommend checking the available links posted on the page to find out how to install the client and how to work with it.
Note: The links will point to the Mac release version. For Windows, the process is pretty straightforward. Download and install the package, then launch it and use the credentials you received from your company or Cisco to connect over a virtual private network.
According to the official information, you cannot install Cisco VPN Client on a Windows Server but since the server resembles with the normal Windows version, you could try to attempt an installation. The official supported platforms are as follows: XP, Vista (x86/32-bit only), Windows 7 (x86/32-bit only), and Windows x64 (64-bit). For more information, you can visit the official website.
