Hello all,

On DPM2010-RC, when I try to select the Hyper-V part of an added host, I get 
the following error:
---------------
One or more prerequisites for protecting this data source is missing.
Ensure that the following prerequisite software is installed on 
bucksrv02.bciglobal.nl and/or all nodes in the cluster:

Windows Server 2008 with
Knowledge Base article 948465 (http://support.microsoft.com/kb/948465)
        AND
Knowledge Base article 971394 (http://support.microsoft.com/kb/971394)
        - OR -
Windows Server 2008 R2 with 
Knowledge Base article 975921(http://support.microsoft.com/kb/975921) 
        AND 
Knowledge Base article 975354(http://support.microsoft.com/kb/975354) 
 
If you have already installed the required prerequisite, refresh the agent 
status in the management tab and try again.
------------------------

If I try to install those updates on the hyper-v machine (a 2008r2 
enterprise machine), the 975921 is for X86, and the 975354 gives me that it's 
already installed on the host.

How do I fix this problem?

Thank you, 

Robert Bleumer

Both 975921 and 975354 have X64 version of the patch. 
(http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=975921&kbln=en-us)
975354 has two patches  on X64 and both needs to be installed. 
(http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=975354&kbln=en-us)
For KB 975354 you need to install in the order below:
    Windows6.1-KB975354-x64-1.msu
    Windows6.1-KB975354-v2-x64.msu


Once you have installed these refresh the agents in the management tab of 
DPM ui and then proceed to creating the protection groups.
