Automated uninstall of SEP 14.x client

Hello there,

I've been tasked with finding a way to automatically uninstall the SEP 14 client from a batch of PCs so another group can install other stuff, then reinstall the client.

Automated installs are easy.  Automated uninstalls would be easy too, BUT.... I cannot find a way to pass the uninstall password to the client in an msiexec commandline.  Is there a public property that can be referenced to pass the uninstall password?

SEPprep will not work and notes about removing a registry entry that holds the password that I've seen don't apply to version 14.

Any ideas or solutions?
