Cisco VPN Client 4.8 fails to install with no error messages

  • I am running Windows XP Service Pack 2 and Symantec Antivirus 10. I was successfully running Cisco VPN client 3.63 and attempted to upgrade to 4.8. The upgrade package reported that it was uninstalling previous client. It then reported that system must be rebooted after which install would complete automatically. After reboot, nothing happened for a while. I then manually re-ran installation package and it appeared to run normally and complete. However, no files were installed in the Program FilesCisco directory! I followed the Cisco instructions for manual uninstall of the VPN client (removing registry entries and some system files) and attempted re-install with same results. I attempted re-install of old client 3.63 with same results. I uninstalled Symantec Antivirus and attempted re-install of Cisco client 4.8 with same results. How can I successfully install the Cisco VPN client, either version?


  • The solution was to use the MSI installer instead of the InstallShield installer. It was actually that simple. We never found out what the problem was with the InstallShield version.
