7.5 Altiris agent deployment via GPO

Hello All

We have successfully installed Agents on 7.1 via GPO.

We have used msiexec to create msi packeges pointing our Notification Server and dediceted Site Server and shere placed on Site Server where full packege is playced.

The command: msiexec /a AeXNSCInstSvc.msi NS="FQDN Notifications server name" NS_WEB="http://FQDN Notifications server name/Altiris" SOURCE_URL=" Site server FQDN and Virtual Directory and Alias (Altiris Agent file location) name/AeXNSC.exe" SERVICE_PARAMS="-c 1024 -p 25"

I have tried the same with 7.5 but does not work.

Should this work in 7.5 ?
