But this problem isn't only isolated to 2.5 client, so I thought a new discussion might attract a bit more attention and feedback.
For 5 or 6 users when I try to install the client as new as version 3.0.11042 (any version, not just the newest) I get a failure:
CustomAction VACon64_Install returned actual error code -536870348 (note this may not be 100% accurate if translation happened inside sandbox)
Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action VACon64_Install, location: C:\Program Files (x86)\Cisco\Cisco AnyConnect VPN Client\VACon64.exe, command: -install "C:\Program Files (x86)\Cisco\Cisco AnyConnect VPN Client\\vpnva64.inf" VPNVA
MSI (s) (44:94) [16:15:05:629]: Product: Cisco AnyConnect VPN Client -- Error 1722. There is a problem with this Windows Installer package.

Before it rolls back, I try to run the command manually which appears to do something, but doesn't fix the problem.
This is the step that is trying to install the service VPNVA, but it fails.
I have cleaned up all the files I know how (which registry entries might I also try?) and rebooted several times, but no luck.
The documented Cisco solution, and what i've been telling frustrated users one after another is "re-image your machine"
Does someone have an idea of what else I can try?
