[Help] Using a Task to install an MSI, but only error 1639

Go to solution Solved by MartinK,

Hello, I am trying to use a task, to install an msi (Baramundi agent) with parameters:

Install by direct package URL -> file://\\srv-xxxxxx\managmentAgent.msi
Installation parameters -> /qn server=xxx

The installation seems to find the file and then gives error 1639 (Commandline parameter error). But the parameters are correct and work fine on the system when installed per cli.

What am I missing or doing wrong? Any ideas?

Please do not provide msiexec parameter to "Installation parameters", it is supposed to contain only custom properties used by installer itself. In other words, parameter "/qn" is not required at all, internal mechanisms will ensure that installation will be silent, that is standard behavior.

But be aware that it won't be possible to upgrade AGENT using this mechanisms, could you please provide more details why you are doing so? Or it was just example?
