I also have this type of problem.
I am trying to create a package file from SIM (Symantec Management Platform MR1 7.1). It downloads and validates the majority of the files but then stops (0kb) for the Workflow Solution Application (symantec_workflow_7_1_kb54090_x64). This then just stops the whole process so I cant do anything else.
I have also tried to install SMP on teh server I am downloading from but it fails in exactly teh ame place trying to copy the workflow folder.
Any help would be much appreciated with this as we seem to be falling at the first hurdle in migrating from Altiris 6 to 7.1 !
(I am also struggling to fing the SIm installation log file ... thsi may help me if anyone knows where it is located)
Thanks
