I ran into this issue while trying to get the Mac version of Cisco VPN Client to run on the only Mac user's system I support. After a little bit of searching I found out that the user's system is 64-bit and the Cisco VPN Client only comes in the 32-bit https://www.warrenheld.com/cisco-vpn-client-for-mac-error-51/ flavor. The easiest way to get Mac OS X into 32-bit mode is to restart the computer and hold the 3 and 2 keys while it boots. Likewise, if your Mac normally boots in 32-bit mode you can hold down the 6 and 4 keys to get it to boot into 64-bit mode. You can check to see what architecture you are running by running this command in the terminal: [bash]systemsetup -getkernelbootarchitecturesetting[/bash] To set your machine to always boot into 32 bit mode enter this command and reboot: [bash]sudo systemsetup -setkernelbootarchitecture i386[/bash] To set your machine to always boot into 64 bit mode enter this command and reboot: [bash]sudo systemsetup -setkernelbootarchitecture x86_64[/bash] Cisco Cisco / OS X /

In my experience, almost every operating system upgrade has needed a update to the VPN client software. Have you checked if there's a newer Cisco client for your office?That said, have you tried uninstalling and reinstalling the Cisco software? Also, OSX's built-in cisco vpn client VPN client works for many Cisco implementations, so works for a lot of people. If possible, I recommend uninstalling Cisco's software an see if you can configure OSX's VPN. I'm currently using OSX's VPN to a Cisco ASA 5510 with SecureID authentication. With OSX 10.6.8 and 10.7.

Conencting to a VPN 3k concentrator can have mixed results, because they haven't updated those things in a while, and they will be end of support from Cisco next year. The OS VPN can be configured in your network properties, and you get to stay in 64 bit mode.
