Since this might affect somebody thinking about updating:

Can somebody explain where to find the queue manager installer for remote nodes?

Before I used the SM download manager to download it. Since there is no separate download link for QM on posersoftware.com/downloads, I looked at the reference manual on page 24, which states: "When you install Poser Pro, it will also install the necessary files for Queue Manager that you need on the installation computer. The separate Queue Manager installer is intended for remote nodes [...]" without giving a hint where that installer was put.

If I am missing something obvious, it's not obvious to me :)
