Scripting

You can use directly the deployment under Distribution|Managed Installation (which is was "wizarded" before but this wizard was always not nessesary since the fields are simply the same)
See here for more info: https://support.quest.com/kb/4300813

you can simply setup the MSI under Distribution > Managed Installation
Since the default choice is MSI you don't need to do much here, even if I prefer to use msiexec /i MSI.MSI /qn als command line and don't use the built in msiexec option (for a multitude of reasons, many versions ago I remember this did not work so well, so the workaround was using msiexec as command line 5 or so?)

Hi, I upgraded as well, but since version 13 or 12.x when KACE introduced the token I stopped using that wizard. The way that I do it here is either via a GPO that runs a simple bat and install the agent or via MDM to deploy the agent.

To get the agent I go to AdminUI > Token > My token and then click on the version ID. 

You will get a nice zip file with everything you need and the MSI will have your FQDN and Token in the name so deploying using msiexec is easier. No need for GUI.

Thanks for the responses.  I have a piece of software that updates about 3 times a year. I used the configuration policies for a couple of things. The uninstaller made it really easy to remove old versions of the software (the update won't remove old versions, and won't install with a previous version installed). And then setting up the new software was really easy with the wizard.  

I guess I'll dig into the managed installation, but it was nice to have the wizard figure out the registry keys for me for the uninstaller.
