Posted by essjae on January 19, 2012


If you have an AMD Bulldozer based CPU, you probably can’t install Windows VPC successfully. AMD Bulldozer based CPUs includes the new FX series (FX-8170, FX-8150, FX-8120, FX-8100, FX-6200, FX-6120, FX-6100, FX-4170, FX-4150, FX-4120, FX-4100)

Could not complete Setup. Please try again.

CAUSE

This issue occurs because of a compatibility issue between Windows XP Mode and AMD Bulldozer-based multicore processors.

Installation instructions

To resolve this issue for OEM partners, integrate the hotfix package into the installation image of Windows 7. To do this, follow these steps:

  1. Download all the necessary files and tools. To do this, follow these steps:
    1. Install the Windows 7 OEM Preinstallation Kit (OPK).
    2. Copy the hotfix package to a folder on the computer. For example, copy the package to the folder C:\Test\Updates.
    3. Copy the Install.wim file from the Windows 7 installation media to the computer. For example, copy the Install.wim file to the folder C:\Test\Images.
  2. Add the hotfix to a Windows 7 image. To do this, follow these steps:
    1. Click Start, click All Programs, click Windows OPK, right-click Deployment Tools Command Prompt, and then click Run as administrator.
    2. At the command prompt, retrieve the name or the index number for the image that you want to change. To do this, type the following command, and then press Enter:
      Dism /Get-WIMInfo /WimFile:C:\test\images\install.wim
    3. Notice the index number or the name of the Windows 7 image to which you will add the hotfix.
    4. Use a DISM command to mount the image by using the index number or the name that you noticed in step 2C. For example, the index number of the image to which you will add the hotfix is 3. The following command mounts Index 3 to a folder that is named “offline” in the test directory:
      Dism /Mount-Wim /WimFile:C:\test\images\install.wim /Index:3 /MountDir:C:\test\offline

      Note You must create the C:\Test\Offline folder before you mount the image.

    5. At the command prompt, type the appropriate command to add the hotfix, and then press Enter.

      For x86-based versions of Windows 7:

      Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\test\updates\Windows6.1-KB2519949 -x86.msu

      For x64-based versions of Windows 7:

      Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\test\updates\Windows6.1-KB2519949 -x64.msu
    6. At the command prompt, type the following command to commit the changes and to unmount the image, and then press Enter:
      Dism /Unmount-WIM /MountDir:C:\test\offline /Commit

Registry information

To use the hotfix in this package, you do not have to make any changes to the registry.

Restart requirement

You do not have to restart the computer after you apply this hotfix.

Windows 7 file information notes
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version Product Milestone Service branch
    6.1.760 0.16xxx Windows 7 RTM GDR
    6.1.760 0.20xxx Windows 7 RTM LDR
    6.1.760 1.17xxx Windows 7 SP1 GDR

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the “Additional file information for Windows 7” section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are very important for maintaining the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.

    I’m running an FX-8120, but this hotfix did not work for me. Anyone know why?

    FX6100 – Worked like a champ – but did have to uninstall xp mode, and the KB958559 refresh package – reboot – install the hotfix, and then reinstall xp mode and then the refresh.
