[Unattended installation for .msi]

hi there,

i use 

msiexec /i "c:/Pulseway_x64.msi" /qn ALLUSERS=1 username=uuu password=ppp Group=ggg server=sss /L*v c:\PulsewayInstall.log

 

but all the endpoint would be assigned to my company's default group, no matter it is  ""organization - site -agent group" or "organization site agent group"  as group parameter. i am wondering that format i need to user to define a group.
