Scripting

Usually you will have MSI files, where an uninstall is easy and also silently.

would unistall completely silent. 

With KACE go to Inventory|Software| <the software in question> and check for Uninstall String.
With this string you can setup a script (if you want to uninstall multiple software in one script)

You also can use the Uninstaller under:
Scripting | Configuration Policies | Windows Uninstalller.
Set this up which produces you a script for this special Software only.

And of course you can use WMIC for doing this in a script for Software where no other way can be found (or multiple software with a similar name)
