Hi matte
Thanks for your hints.
Hence the underlying server is a Windows 2016 .Net is installed in version 4.6; also the Message Queuing service is running - but during SnapCenter install there was a pop up, warning that there is an outstanding reboot (although I just reboote beforehand!) and that install of message queuing could fail - but it went away without intervention and installation finished without complains.
Going from job monitor to view logs revealed only the aformentioned line ...
my theory is at the moment:
because the first attempt of install the plugin failed, I tried to re-install by "modify" the host (that is: SnapCenter host).
In the summary I get the following then:
pay attention to "Plug-ins: none, Version: none" - maybe the wizard does not select anything to install ...
in contrast the picture when adding the host:
Both, version and plugin are mentioned ...
Anyway - I removed the host and re-added it, filling out all the fields of the wizard.
Now the plug-in installation failes complaining about an "incorrect parameter" in the job details:
But the log itself does not give a clue to me which parameter is wrong ...
... very frustrating ...
