Wix: single MSI instead of msi + cab

windows-installerwix

My Wix project creates install.msi and cab1.cab. How can I have it bundle everything into the msi? I will likely use 7-zip SFX to work around this but I have seen other apps with only a single msi.

You didn't post any source but I assume your wxs file has a Media element. Just set the EmbedCab attribute to "yes" in MediaTemplate e.g.

<MediaTemplate EmbedCab="yes" />

A reply by Bob Arnson in this thread:

Yes, that's the behavior of the Add/Remove Programs applet. It always uninstalls MSI packages in basic mode after prompting. The only thing you can do is set ARPNOREMOVE to force a user to use maintenance mode -- and surface a Remove option in your maintenance UI.

Passing command line args to MSI from WiX bundle

Your MSI needs to define a property like so:

<Property Id="SOMEPROPERTY" Value="Default"/>

You can then set this property from the bundle:

<MsiPackage SourceFile="<package>.msi" Id="SomeId">
    <MsiProperty Name="SOMEPROPERTY" Value="[SomeProperty]" />
</MsiPackage>

After this you can set the property in the Bootstrapper as described here: WiX Bootstrapper: How do I set burn variables from the command line?

Notice that SomeProperty is a Burn variable which you have to define:

<Variable Name="SomeProperty" Type="string" Value="DefaultValue" />

Update:

In the MSI you are then able to do a registry search based on this property:

<RegistrySearch Id="GetSomeValue" Root="HKLM" Key="SOFTWARE\<Manufacturer>\[SOMEPROPERTY]" Name="<ValueName>" Type="raw" />
