We are pleased to announce the release of Windows Installer v3.0 (MSI3.0) RC1. This release contains improvements to simplify application servicing. The redist package will not install on WinXP-SP2/RC1 or Win2k03/SP1.

New features in the MSI3.0 / RC1 release:

  • Opt-in for Patch uninstall
    Authors need to explicitly mark patches in order to support uninstall.

  • MsiPatchMetadata
    The new MsiPatchMetadata table provides additional information about a patch - including whether it supports uninstall

  • PatchWiz.dll
    PatchWiz.dll, the SDK tool used to create MSPs has been enhanced to support the new MsiPatchSequence and MsiPatchMetadata tables. It can also generate automatic patch sequencing information that should suffice for simple product servicing. PatchWiz has been optimized to significantly reduce the time taken to create patches.

  • Standard Command Line Options
    MSI30 and update.exe support the same standard command line options to make it easy for administrators to control display, reboot behavior, install, uninstall, log generation and applying updates. Try msiexec /? after you install the RC1 bits.

    Thank you for participating in this beta program. We look forward to your valuable feedback.

  • Smaller Patches for Assemblies
    MSI30 adds support for smaller binary delta compression patches for assemblies.

  • Patch Sequencing Whitepaper
    MSI30/RC1 includes a whitepaper on patch sequencing to help product teams design and implement servicing strategies that can take advantage of Patch Sequencing.

    Try going to V5.Windowsupdate, because it used to install 3.0 when you get part way into the checking process.

    Watch out! I'm on the V5 Windowsupdate beta and installed the MSI3.0 RC1 and could not install any .msi files until I uninstalled it. There may be some version incompaitibilities.

    "Installation Summary


    The following updates were installed successfully:


    Microsoft Background Intelligent Transfer Service (BITS2) Client version 2.0 Beta
    Windows Installer v3.0 RC1"

    And we are off and running. I saw a demo of this a few weeks ago. If it is the same thing, they were talking about combining Windows and Office update. With all the holes in Office this should have been done a long time ago.

    MrMunka is right about installer errors. Some installers would not play well with RC1...had to uninstall it.
