Anybody know how to install an MSU in Vista? I have tried several methods with no success and found nothing on this forum.

Thanks

The .MSU file format is a new package type for Windows Vista (and above) which contain updates to the Windows platform. These .MSU packages have an executable called wusa.exe to which you can pass command line switches. This separate EXE method is similar to the way msiexec.exe is the runtime for.msi packages. The wusa.exe is more formally known as the Windows Update Stand-alone Installer. See this: "Description of the Windows Update Stand-alone Installer (Wusa.exe) and of .msu files in Windows Vista" at http://support.microsoft.com/kb/934307

For now, you need a cmd component that simply calls wusa.exe. Please file a feature request about adding an "msu" type component similar to the msi component type.

I've implemented this in build 1.7.26073.0. Please let me know if this works for you. -dB.
