Power edge R910 question

Hi,

We have a Poweredge R910 and we want to install the Administror Management software on this server, but when run the setup we see a page that says: Loading prerequisite information. Please wait...
But after that nothing heppens. is it possible instead run the SysMgmt.msi? We did try to run this msi and get a warnning that we should run the prerequisite first and we can ignor this an go ahead with install.

we did download OM-SrvAdmin-Dell-Web-WIN-7.4.0-866_A00

is this the right version? we now that our system is 64 bit so can we just run the SysMgmt.msi?

Thanks
