In Windows Vista, the Package Manager tool can install only the first package when you extract two or more packages to the same folder.

For example, consider the following scenario:

• On a computer that is running Windows Vista, you create a C:\Temp folder.
• You download the following hotfix packages to this folder:
  • Windows6.0-KB929761-x86.msu
  • Windows6.0-KB932590-x86.msu

  These hotfix packages are for hotfix 929761 and hotfix 932590.

• You run the following commands to expand the hotfix packages:
  

  c:\temp>expand c:\temp\Windows6.0-KB929761-x86.msu -F:Windows6.0-KB929761-x86.cab c:\temp
  c:\temp>expand c:\temp\Windows6.0-KB932590-x86.msu -F:Windows6.0-KB932590-x86.cab c:\temp

• You run the following commands to install the packages:
  

  start /w Pkgmgr /ip /m:c:\temp\Windows6.0-KB929761-x86.cab
  start /w Pkgmgr /ip /m:c:\temp\Windows6.0-KB932590-x86.cab

In this scenario, Package Manager installs only the package for hotfix 929761.

When this problem occurs, information that resembles the following may appear in the Cbs.log file:

2007-07-25 13:17:05, Info CBS Pkgmgr: called with: "Pkgmgr /ip /m:c:\temp\Windows6.0-KB932590-x86.cab"

DistributionComp: 1, RevisionComp:1, Exist: 1

In this example Cbs.log file, Package Manager indicates that it will install the .cab file for hotfix 932590. However, it actually installs the Package_1_for_KB929761~31bf3856ad364e35~x86~~6.0.1.1 package. This is the hotfix 929761 package.

Note: This problem also applies to Windows Server 2008.
