Hi:
Thank you very much for your help. With your answer I cand found the cause of error (Servive of Altiris).
The Altiris Service (AeXSvc) isn't listed in Service List. But I found in Internet how recreate this service form Command Promt.
"Create the service is to open a command prompt and Change Directory into the c:\windows\microsoft.NEt\framework64\v4.0.30319 folder and run installutil.exe "c:\program files\altiris\notification server\bin\aexsvc.exe".
After this Task I Ran again the SIM and the upgrade to Altiris 7.6 was sucesful.
