    <p>Having one .MSI package launch another .MSI package from "within" itself is called a <em>nested install</em>, and it's <a href="http://blogs.msdn.com/windows_installer_team/archive/2006/05/12/595950.aspx" rel="nofollow noreferrer" title="bad juju">bad juju</a> (see Rule 20). Windows Installer has some global data that it uses to manage the current install, and it doesn't handle well multiple installs at the same time. For the same reason, if you start one install and then try to start another while the first is still in progress, you'll usually see a pop-up to the effect of "another install in progress, please wait until it's done".</p> <p>You can have a program, usually called a bootstrapper (I think that's what you're referring to) which is itself not an install package, but which <em>contains</em> an install package (such as an .MSI or an .EXE) as a resource, possibly compressed. The action of the bootstrapper program is to extract/expand the resource to a file, commonly in a <code>%TEMP%</code> directory, then either launch the extracted .EXE or run MSIEXEC on the extracted .MSI. The bootstrapper can contain multiple resources and extract+install them one by one, if you need to install prerequisites before the main package. Or you can ship multiple packages as separate files, and have the bootstrapper execute/install them directly from the distribution media one by one, or copy them down to the target machine and run the series of install from there, or...</p> <p>WiX itself does not get installed, no. It's a tool with which .MSI packages can be built. The WiX project has on its wishlist a generic bootstrapper program, but it hasn't been implemented yet. There are other bootstrappers available, e.g. <a href="http://msdn.microsoft.com/en-us/magazine/cc163899.aspx" rel="nofollow noreferrer" title="this one">this one</a>.</p> <p>You won't need a custom action -- in fact, since the bootstrapper isn't itself a Windows Installer installation package, "custom action" has no meaning to it. And, if you're familiar enough with CAs to know about managed/unmanaged/DTF, then you know enough to avoid custom actions whenever you can. (grin)</p>

    1. COI don't understand why it should be bad juju. Microsoft itself does this. The SQL Server 2005/2008 installers, for example, are actually made up of multiple MSI files, which are executed depending on which features you choose under custom installation.

    2. COJon, the SQL Server install is driven by an external program that installs each MSI in a sequence (aka: chain). They do not have one MSI calling another MSI (aka: nested). Nested installs are deprecated.

    3. COThis is not what I'm talking about - I am not "launching" or running this other MSI at all. This "other" MSI is simply the original/outer/whatever MSI that is being run.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
