Altiris 7.1 SP2 MP1 - Inventory agents cannot deploy

Hi All,

i just updated my NS to 7.1 SP2 MP1.

After that, i found i cannot deploy Inventory Agent to client computers.

i look into the "Inventory Plug-in Install" Policy and found "Package name:   Inventory Plug-in for UNIX/Linux/Mac Package".

i don't know whether it is related.

Please help.
