After installing Cisco VPN Client Windows 8 64Bit you get the error reason 442: failed to enable virtual adapter when trying to connect.

Solution:

• Open regedit
• Browse to the Registry Key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CVirtA
• Select the DisplayName to modify, and remove the leading characters from the value data up to the last “%;”
• for 64 bit; change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows” to “Cisco Systems VPN Adapter for 64-bit Windows”
• for 32bit; change the value data from something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter” to “Cisco Systems VPN Adapter”

Reboot to test, the above solution worked for me on Cisco client version 5.0.0.07.0240 64bit.
