Hello J6720Dell,   It does look like you have the latest. Can you try download a fresh copy from these link to make sure you got a good download.   for 14G and newer [URL]   for 11G through 13G [URL]  
I am trying to import the catalog for Dell Server updates from [URL] to MECM but when I do the Dell Open Manage Inventory Agent (for Dell Servers) is not present.  I have an older installation of Dell Server updates for MECM (SCCM) but that catalog is months out of date. Do I have the catalog for Dell server updates correct? Is this tool still supported by Dell? I'm currently using the partner catalog for Dell Business Client third party updates for MECM and it's working just fine but the sever side of things is giving me problems.  
No Dell OpenManage Inventory Agent for Dell Servers in dellsdpcatalog.cab
