Scripting

You will need to investigate if this application can be installed from a single command line in order to do this as a managed installation, otherwise you may need to write a script.

Can you share what you actually know?

This is what I found

/i "$(KACE_DEPENDENCY_DIR)\vfagentsetupx64.msi" INSTALLATIONKEY="Key information" CONFIGURATION="$(KACE_DEPENDENCY_DIR)\config information" /qn

So, reading between the lines here maybe the command line should look like

Msiexec.exe /i vfagentsetupx64.msi" INSTALLATIONKEY="Key information" CONFIGURATION=config information /qn

If you create a zip file that includes the msi file and the config file, both in the root of the zip, then create a managed installation to deploy using the zip, the may be no need for script as the Managed installation should see, what will be a local config file to the msi?
