I am trying to install Forefront 2010 Endpoint on my SCCMr3 sp2 server. This is on a Win2008r2 server. I keep getting an error stating I need to upgrade to SCCM r2 sp2. I ran the hotfix kb2271736 but didn't help. My sccm version is 4.00.6487.2000 The pre-requisited say that should work. Can anyone assist with this? This is in my test environment but I do need to get it working before putting into production.
