If you download the latest version(as of this writing 5.0.07.0440) of the latest ipsec vpn client for the Cisco ASA you may notice an error when trying to connect through Windows 8. In order to get around this error and make it work you must modify your registry. It is a very simple tweak. Open regedit and browse to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesCVirtA. Once here look on the right hand side for DisplayName. You will see its current setting is something like “@oem8.inf,%CVirtA_Desc%;Cisco Systems VPN Adapter for 64-bit Windows”. Simply change this to “Cisco Systems VPN Adapter for 64-bit Windows”. Once this is finished close regedit reboot your PC and voila your vpn will now work!
