Here is ONE solution we have FOUND
We also posted all together here:
Just spent two days with that....
Problem is that the repository pull of the 2966 content failed.
Fixed in today's DAT updates. I've just successfully downloaded 2967 from the ftp repository.
We had the case WHERE Absolute no AMCORE Update was DONE after migration to 10.5.1 with Framwork 5.0.4 since Last THURSDAY. So i don't think the DAT Update will solve it....
See after our FIX/Solution we have 2966 on clients.
