I have Windows 8 with all anti-virus disabled.
When starting AnyConnect, I first get:
Failed to perform required client update checks. Contact your system administrator.
Click OK, and it downloads the 3.1.02040 install.
It downloads and begins installing. Eventually I get
Failed to install AnyConnect Secure Mobility Client 3.1.02040. A VPN connection cannot be established.
I am on a home network, no other VPN or corporate firewall.
Thanks,
Steve
