Windows Installer 4.5 versions

  • Article

As you all may already know the final release of the Windows Installer 4.5 Redistributable and SDK are now available.

The current version of Windows Installer is in the form; major.minor.build.update. We have received a few questions regarding the differences in the "build" and "update" fields of the version of Windows Installer 4.5 installed across different supported Windows Operating Systems . I will try to explain what these differences are and why they are expected.

The Windows Installer 4.5 redistributable can install on the following Windows Operating Systems:

Target Operating System

Windows Installer 4.5 version

Windows Vista RTM

4.5.6000.20817

Windows Vista SP1, Windows Server 2008

4.5.6001.22162

Windows XP SP2, Windows XP SP3, Windows Server 2003 SP1, Windows Server 2003 SP2

4.5.6001.22159

Windows Vista RTM build number is 6000, while Windows Vista SP1 and Windows Server 2008 RTM are build number 6001. Hence, to comply with the different OS build numbers and applicability logic on Vista RTM and Vista SP1/Server 2008 operating systems, the Windows Installer binaries are built from the Vista RTM and Vista SP1 servicing branches respectively.

The "update" field is based on the OS revision number.  Since the redistributable packages to install Window Installer 4.5 on the different target operating systems are built from different Windows servicing branches, the revision number is different for each.

However, the different versions have no effect on the functionality provided by Windows Installer 4.5.

    http://support.microsoft.com/kb/929467/en-us is the KB article you are looking for. This has not been addressed in Vista SP1 or in Windows Installer 4.5.

    Can a Setup use 4.5 features (like transaction processing) in place until the reboot since MSI 4.5 redist installation requires a reboot?

    Hey Holger -- Deferred reboot is supported on Windows XP and Server 2003, but not for Windows Vista and Server 2008 systems.

    >>> Deferred reboot is supported on Windows XP and Server 2003, but not for Windows Vista and Server 2008 systems Thanks Tyler, but does that mean that transaction processing can be used in place until the reboot? Cause it does not work for me.

    Just to confirm, since there are different redist installer for different OS, each application installer has to package all redist installers, detect the target OS and launch the OS specific redist installer?  Why can't there be a single redist installer that applies to all OS?

    I want to use the fourth field in the Product version of MSI. Whether the Windows installer considers the fourth field or not?

    In one of our test setup we are installing our application developed using VS2005 along with the VS2005 redistributables. The machine have dual boot system with Win2000 in d: and Win2003 in c:. The installation fails. Without the redistributables in the installer the installation proceeds smoothy.However for VS2005 developed application we need to install the redistributables.

    I am still getting the error that says windows installer service could not be accessed even after installing WI4.5. I have tried all the solutions given by Microsoft and none of them worked for me. Is there a way to fix this? Thx
