Windows 2008 SP2 VM - Can't install KB2230887 hotfix for Dynamic Memory

I have a Windows Server 2008 SP2 Standard VM x86 VM running on a Windows 2008 R2 SP1 host server. I have other VM's running Windows 2003 which are using Dynamic Memory on this server. However, I can't seem to get Dynamic Memory working on the Windows Server 2008 SP2. SP2 is installed and I've installed the latest Integration Components. When I downloaded the hotfix http://support.microsoft.com/kb/2230887, I get two options: vista sp3 x86 Fix324410 vista sp3 x64 Fix324410 Neither of these install on my Windows 2008 VM. I get the message "The update does not apply to your system" for both. What am I doing wrong? Thanks... dbaddorf
