Troubleshooting Cisco VPN client

Before starting troubleshooting, Let us see what VPN is and what it requires to perform its intended function.
A VPN connection is the extension of a private network that includes links across shared or public networks, such as the Internet. VPN connections (VPNs) enable organizations to send data between two computers across the Internet in a manner that emulates the properties of a point-to-point private link.
During installation process, an error 0x8004a029: Couldn't install the network component", might have occurred.
Error 0x8004a029 means that the maximum number of filter devices for the system has been reached. Other similar software (3rd party firewalls, etc.) install filters. You can 
either attempt to remove other software that has installed a filter, or attempt to increase the following registry entry value to allow more filters to be installed.
A filter driver is a Microsoft Windows driver that extends or modifies the function of peripheral devices or supports a specialized device in the personal computer. It is a driver or program or module that is inserted into the existing driver stack to perform some specific function.
Hence in order to install VPN properly increase in maximum number of network filters is required.
Now let us see the steps to change the system’s registry value to increase the maximum number of filter so that VPN client could install filters in conjunction with its network component.
1.     Open Registry Editor.
