Hi, When i'm updating My Dynamics AX 2012 R2 CU6 to CU7, all have passed well only the AOS Service, i had an error in installation.
Object Server 01: Message System could not be initialized. Microsoft Dynamics installation has an old version of the text file (axsysen-us.ktd).
Revision 871 or higher is needed.
i didn't find any way to start the service, so i installed another AOS service until i find somthing to resolve my problem.
we developped some modules on the AOT but i don't think that this is the reason to fail the updates to CU7.
