tintim, Welcome to McAfee Community.
Is the multi-platform client available in your Master Repository? Let's first make sure you have the latest client and MOVE extensions. You can update them from "Software Manager".
Thanks Moe for the suggestion
The multiplatform client is available and I did check in the software.
I also updated all licensed s/w as well via Software Manager
Unfortunately I've had to disable 5.9 EPO and 4.6 MOVE products as an update from midnight 15th made the VSA available (according to event logs) and some of the systems crawled to a stop. We think this might due to the system not yet fully configured (due to the above) and elements of the old 3.6 is still resident on some of the servers.
We'll be revisiting this installation after following KB KB74700
Thanks for trying to help
