Loupedeck software does no longer work after installing Options+

If you have just installed or updated your Logitech Options+  software and notice that your Loupedeck software no longer works, you will need to update your existing Loupedeck software to the latest 6.0 version. This problem arises because both software applications utilize some common service components.

Download and install the software here:

Loupedeck 6.0 for Windows (link) or Loupedeck 6.0 for macOS (link)

Please read more about the 6.0 release and its significance to the plugins in this article.
