We use a Cisco VPN Client (v5.0.3) to connect to our corporate network. A user came to use today saying their VPN client was missing. We had a look, and couldn't find it, so reinstalled. However, when we rebooted after installing, the installer launches again, and tries to uninstall the client. We have to click cancel to stop the uninstall from happening.
We've checked in the registry at HKCU\Software\Microsoft\WIndows\CurrentVersion\Run & RunOnce & in HKLM\Software\Microsoft\WIndows\CurrentVersion\Run & RunOnce, however there is nothing in there to launch the uninstall. We've also check the Startup items, and MSConfig, there appears to be nothing trying to launch the uninstallation.
When the uninstall is happening it looks like it's the standard MSIEXEC process that's running, and is probably running with the Cisco setup vpnclient_setup.msi.
Where else could the uninstall be being launched from?
