  1. Hi Stefan!

    Since the first cumulative update we have problems when installing it every month. With the first cumulative updates the language independent file gets stuck or takes a very long time. After we cancel it and reboot the virtual machine, the language dependent file is working and also the rest of the update process. With the uber package we have the same behaviour. This is happening on a single server environment and also on multi server environments. Do you have any idea what the problem could be?




    1. Hi Rene,
      I have not seen this behavior. Installing the fixes takes some time but always succeeds on my machines. If you need assistance to get this isolated I would recommend to setup a repro in a virtual environment with snapshots to ensure that it can be easily reproduced and open a ticket with Microsoft support to get assistance with the analysis.
