Hi,
Please, revise your update and change the return code.
I did the publish like the example "Symantec Endpoint Protection"In this documentation it's wrote to put "1" as return code for Success + Reboot.
Return code = 0x00000000, Result = Failed, Reboot required = falseYour Package require return code "0" for success.
Please, revise your update and change the return code.
