Commented Unassigned: Custom Update is shown as inapplicable [327]

Hello,

today I tried to create and distribute a custom update (batch-file-execution) with version 1.3.1411.09. Creating the update worked, but installation on clients failed (error FFFC). So I downloaded the latest version 1.3.1511.15 and tried the same here. The update appears in WSUS correctly but is shown as inapplicable for the clients (consequently they don't get the update).
It was exactly the same procedure as I had done with the old version 1.3.1411.09.
Can someone help me here? How can I execute batch-scripts via custom update (for uninstalling old Java versions)?

Thanks in advance.
