    Hello Yong
    Thanks for your reply.
    Outgoing Internet is all open and Windows Updates are all installed on that device.
    I've downloaded the last MdatpScanAgentSetup.msi and run it again, without uninstalling the last installation. The certificate got renewed and is valid for another year.

    Thanks,
    Joerg Renggli - LAG
