Installation instructions

To manually install the update packages, run the following command from an elevated command prompt:

msiexec.exe /update <package_name>

Note In this command, the placeholder <package_name> represents the actual package name.

For example, to install the Update Rollup 5 Preview package for a System Center 2012 R2 Virtual Machine Manager server (KB3011473), run the following command:

msiexec.exe /update kb3011473_vmmserver_amd64.msp

Important As of Update Rollup 5 Preview, this step is no longer required.

Important The System Center Virtual Machine Manager DHCP Server (x64) component must be manually updated on all VMM Hyper-V hosts. If this component is not updated, virtual machines may not be assigned an IP address for several minutes after the restart of the VM. (Eventually, the VM receives the IP address and otherwise functions as usual.) To check the version of the VMM DHCP agent, run the following command from an elevated PowerShell Command Prompt window on the host:

Get-WmiObject -Class win32_product -Filter 'Name = "Microsoft System Center Virtual Machine Manager DHCP Server (x64)"'

If the version is earlier than 3.2.7828.0, you must update the agent. To update the agent, follow these steps:

  1. Uninstall the old version by running the following command from an elevated PowerShell Command Prompt window:

    MsiExec.exe /X <IdentifyingNumber>

    Note You can retrieve the value of the <IdentifyingNumber> placeholder from the output of the Get-WmiObject PowerShell command that you ran earlier.

  2. Copy the Dhcpextn.msi file from the VMM server after you apply Update Rollup 5 Preview for System Center 2012 R2 Virtual Machine Manager to your Hyper-V hosts. By default, the file is located in the following folder on the VMM server:

    \VMM_installation_folder\SwExtn\DHCPExtn.msi

    Note The placeholder VMM_installation_folder represents the location where VMM is installed. By default, this is the following folder:

    C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager\SwExtn\DHCPExtn.msi

  3. Double-click the file to start the installation, and then follow the steps in the wizard.

    Note If you also have the administrator console installed on the VMM server, you should install the updates in the following order:

    • Update Rollup 5 Preview for the administrator console

    • Update Rollup 5 Preview for the VMM Server

Between these two installations, the VMM server might create one critical error log under the VMMLogs directory. This occurs because the administrator console shares some DLLs with the VMM server, and version conflict could lead to the logging of the critical failure. To resolve this issue, install both of the updates on the VMM server that you use to start the VMM service.
