I'm having trouble uploading AnyConnect Client Images to my ASA 5510. I've never seen this error before and can't find it posted online. I've tried uploading various AnyConnect files with the extension mst, exe, targ.gz, and msi files. I'm downloading them directly from the link shown in the ASDM that points me to the Cisco software download page: Products Security Virtual Private Networks (VPN) Cisco VPN Clients Cisco AnyConnect VPN Client Cisco AnyConnect VPN Client v2.x AnyConnect VPN Client Software
I'm running ASDM 6.3 and ASA 8.3(2)
svc image disk0:/anyconnect-win-2.5.
g 1 regex "Windows NT"
Invalid file format
ERROR: Unable to load SVC image - extraction failed
