our asa 5540 vpn original use anyconnect 2.0.0343(ASA 8.02). When we upgrade to 2.1.0148(ASA 8.03), some windows xp's client unable upgrade. We try to remove 22.214.171.1243 via add/remove programs or use msiexec command and install 126.96.36.199 via Web or MSI file. Some client always show "the vpn client driver has encountered an error".
