Windows Installer 4.5 beta 2 – coming soon (and a chat too!)

Hello everyone! First off, I wanted to let you know that I have re-joined the Windows Installer (MSI) team as a Lead PM, so you all will be hearing a lot more from me in the future <grin>

I have a few exciting announcements to make today:

  1. I know you all have been wondering what has been up with Windows Installer 4.5, and I am pleased to announce that we plan to release Beta 2 within the next few weeks. If you would like to access the beta program, please read Robert's prior posting on this topic. There will be an announcement posted to the blog when the Beta 2 is available. Your feedback on beta 2 is welcomed and also critical in this stage of our release, as this is our last scheduled beta before we RTM.

  2. We have also scheduled an MSDN Technical Chat on Windows Installer 4.5 on April 3, 2008 at 10:00 AM (Pacific). If you have not participated in these chats before, they are a great forum for you to interact directly with members of the team! Click here to add the chat to your calendar so you don't miss it!

Please stay tuned to the blog for more exciting announcements coming soon ...

    Hi is it only me that have problem with installing ‘office2003-KB945432-FullFile-ENU.exe’?

    Hey MSI team, I didn’t exactly understand the wording used in So do you mean that you meant to do major changes in 4.1 but couldn’t? Are there any minor changes in MSI in Vista SP1? MSDN states that MSI in Vista SP1 adds "multi-package transactions and embedding the user interface of a child Windows Installer package inside a parent installation session".

    Hey does your team (MSI) also handle WUSA.EXE and PKGMGR.EXE, and Update.exe (Hotfix installer)??? I have some major issues with Vista and I wish someone would answer/explain:

    1. Windows Vista uses Package Manager (Pkgmgr.exe) OR Windows Update Standalone Installer (Wusa.exe) to install software updates and hotfixes. However, these do not support the various command-line switches like Windows XP’s Package Installer (Update.exe) did. Much of the functionality from Update.exe is missing. For example, there is no way to skip backing up uninstall information for hotfixes using the /nobackup or /n switch. Windows Vista backs up files before installing hotfixes to the %Windir%WinSxS folder. Since the backing up of files cannot be skipped, this folder can get considerably large and take up an extremely high amount of disk space. Any solution to this, except staying with XP?

    2. It is not possible to slipstream service packs or hotfixes into the core operating system files as was possible with Windows XP, Windows Server 2003 and Windows 2000. Will this change for Vista SP2?

    Hello all, and thanks for leaving feedback!

    Anonymous: Looks like there may be some incorrect information in the documentation and I’ll have our writers correct it. Vista SP1 just contains bug fixes. New features will be in our MSI 4.5 relese (check out the chat for more information!)

    Someone: Unfortunately, these are not our technologies. The Windows Update team has a blog at … I would suggest trying that one out.
