I am using a windows 7 virtual machine 64 bits.
I got this error when trying to connect vpnclient. It was working still recently , and now is giving this error
I tried solutions like copy a iphlpapi.dll from another place where it is running ok, reinstall vpnclient, run antiviruses to clean vm, Nothing works.
I saw some help from this discussion group from year 2007. I tried that too with no success.
Thanks in advance for any help or orientation
This below is what is in the log:

Hi marcebil,
This is definitely a hard one since not much people uses a product that is already end of life and end of support since 2014, the behavior you are describing and the error normally happens for this 2 reasons:
1- The OS did some changes on the Virtual Adapter that are affecting the VPN Client, in this case you probably already followed this recommendations:
Enable Virtual Adaptor before connecting -or- Disable the ICS (Internet Connection Sharing) service in Vista --> ***as you can see this is from Windows Vista and there is a bug for this behavior CSCsv31383***
2- A 3rd party software could be also interfering with the VPN client not allowing the VA to come up, this could be caused for an AV/AM/FW....
Considering you are asking for options to get this working with the legacy VPN client im not sure if this help but i would like to give you some suggestions:
1- Configure AnyConnect with ssl or ikev2
ASA SSL:
ASA IKEv2:
Router SSLVPN:
Router FlexVPN:
*** this options will requires licenses considering the amount of users that will use the service and even to download the anyconnect client from cisco.com***
2- Another option without a license will be using the Windows Native ikev2 client:
ASA:
Router:

Hope this helps!
