Upgrade SCVMM 2008 R2 SP1 to Update Rollup 2

Hi, I am running SCVMM 2008 R2 SP1 and want to upgrade to the Update Rollup 2, but I went to the web site for the KB 2691812.

and tried to run Windows Update, but can't find "Update Rollup 2"

So then I tried to download the update packages. I received an error when trying to install KB2701207:

The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.

When I open SCVMM 2008 R2, I am running Version 2.0.4521.0 Service Pack 1

Thanks
