Advice on deploying the Openmanage Server Administrator through DMC?

I have installed Dell Management Console and am trying to get my servers Discovered and Inventoried. I have pushed the Altiris Agent successfully. Now I am having trouble installing Server Administrator. What kind of install file is required by the Dell OpenManage Server Administrator Deployment Wizard? I have the .exe file used to install OMSA directly onto a system but when I choose that file to use with “Create a new Software Delivery Package” I get the error message “Select a valid Dell OpenManage Server Administrator install file.” Any ideas?
