Cisco AnyConnect Client Image Error: Invalid File Format - Unable to load SVC Image - Extraction Failed

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)

[OK] webvpn
svc image disk0:/anyconnect-win-2.5.0217-k9.pkg 1 regex "Windows NT"
       Invalid file format
ERROR: Unable to load SVC image - extraction failed

Turns out the MD5 check sum was being changed as the file was downloaded. I downloaded the file using a different connectioned, saved it locally to a USB stick, then I was able to load it into the ASA without and issues. Thank you everyone!

I know I should be doing this via the CLI. So, I followed the directiions located here and it also fails on step 2.

Here what I typed and the output. Same error as stated previously.

This is now even making less sense to me.

ASA# sh run webvpn
 enable FIOS
 svc enable
 tunnel-group-list enable

ASA(config-webvpn)# sh webvpn svc
SSL VPN Client is not enabled.
