When I attempt to install Cisco AnyConnect 4.9.01.0100 (and other versions) installer, i receive the following error message "vpnclient cannot be installed on this computer. A version of TUN is already installed on the system that is incompatible with the AnyConnect client"

I have deleted the all vpn applications that I know of (e.g., Cisco VPN client, Shimo, etc.). Rebooted, repaired permission and still the intsaller will not install the app. Same error message.

Did you install openvpn by chance?  Also can you loo for hte following files.

/System/Library/Extensions/tap.kext
/System/Library/Extensions/tun.kext
/System/Library/StartupItems/tap
/System/Library/StartupItems/tun
/usr/local/sbin/openvpn
/usr/local/sbin/openvpnstop
/usr/local/sbin/openvpnstart
/Applications/OpenVPN.app

/Library/Extensions/tap.kext
/Library/Extensions/tun.kext

If these do exist delete them or move them to another location and try installing again.  Just for reference I run Viscosity and TunnelBlick (both openvpn gui apps) as well as Cisco VPN client with no issue.  You may want to try the cisco client that is hosted here.

That is the one for leopard and tiger it is hosted at McMaster University and has there config in it but you can remove them and import yours, this is the most stable Cisco client I have found.  Hope this helps please let me know your outcome.

Hey thanks a lot for the guidance here. The culprit was these two intries:

/System/Library/StartupItems/tap
/System/Library/StartupItems/tun

Had to restart after removing them. Then was able to install the AnyConnect client.

Thanks,
Ken

I am currently experiencing the same issue but found no trace of the folders mentioned above by norcaldude. I did find a CiscoVPN folder or something very similarly named and removed them. I then restarted my computer, and I'm still being given the same piece of information. I uninstalled my previous version and removed all backups of the folders I had made while working from my computer (trash was deleted as well).

Thanks for the help.

Finally found the following files:
/Library/Extensions/tap.kext
/Library/Extensions/tun.kext

Installed without a hitch following a restart. Thanks!
