Hello
I have generated the XML file (with MOPZ) and downloaded the files in "..\EPS\in" folder.
You should consider using a different drive for SUM and also for the downloaded files.
Putting the downloads for the upgrde would be better kept in a separate directory rather than keeping them under the "..\EPS\in" folder.
Regarding multiple kernel archive files in the "..\EPS\in" folder, check the stack file which are the kernel files select during the stack file creation.
Remove all the kernel archive files except the ones mentioned in the stack.xml file.
Repeat the phase in SUM.
Regards
RB
