I have Anyconnect Secure Mobility Client v3.1.03103 installed on Win7 Pro, which works fine with both my corporate vpn, and a number of customer vpns. For a particular customer though, The VPN setup fails and asks me to download and set up AnyConnect VPN Client 2.3.2016.
I have read other entries suggesting replacing VPNManifest.dat for machines running 2.5, but that doesn't appear to work here. Further, I have two directories, c:\Program Data\Cisco\Cisco AnyConnect Secure Mobility Client\ and c:\Program Data\Cisco\Cisco AnyConnect VPN Client\
Alternatively, can the two clients coexist?
