The default value for TARGETDIR [1] is C:\ but tools like VS.NET setup and
deployment projects add a type 51 CA (set property from formatted text) to set
TARGETDIR to [ProgramFilesFolder][Manufacturer]\[ProductName]. Also TARGETDIR
can be specified on the command line to specify where you want the application
installed. So Windows Installer defaults TARGETDIR to C:\ (actually ROOTDRIVE
property) if TARGETDIR was not specified by a certain point (CostFinalize) in
the installation sequence.
The WiX convention seems to be to set INSTALLDIR to the above path and leave
TARGETDIR at its default.
A VS.NET setup and deployment looks something like this in WiX:
<Directory Id="TARGETDIR" Name="SourceDir">
<Component Id="ProductComponent" Guid="MYGUIDHERE">
<File Id="MainProgram" Name="prog.exe" Source="prog.cab"
DiskId="1" />
</Component>
</Directory>
<!-- Sets the TARGETDIR property to a path based on ProductName property-->
<CustomAction Id="SetTARGETDIR" Property="TARGETDIR"
Value="[ProgramFilesFolder][Manufacturer]\[ProductName]"
Execute="firstSequence" />
<InstallUISequence>
<!-- Set TARGETDIR if it wasn't set on the command line -->
<Custom Action="SetTARGETDIR" Before="CostFinalize">TARGETDIR=""</Custom>
</InstallUISequence>
<InstallExecuteSequence>
<!-- Set TARGETDIR if it wasn't set on the command line -->
<Custom Action="SetTARGETDIR" Before="CostFinalize">TARGETDIR=""</Custom>
<InstallExecuteSequence>

Subject: [WiX-users] What exactly is SourceDir?
In all of the samples you see fragments like this:
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="MFR" Name="Wieser Software Ltd">
<Directory Id="INSTALLLOCATION" Name="Prog">
<Component Id="ProductComponent" Guid="MYGUIDHERE">
<File Id="MainProgram" Name="prog.exe" Source="prog.cab"
DiskId="1" />
</Component>
</Directory>
</Directory>
</Directory>
I don't really understand what the SourceDir is above, even though it seems
to be required (you get a warning if it's not there).
Looking through the logs, the SourceDir always seems to be set to the path
of the msi file that's run, if its on a network, or even a drive created by
subst.
However, the TARGETDIR seems always to be set to C:\
Also, why are the other directories listed as a child of TARGETDIR, when
they can in fact be located anywhere in the file system. Is it just a
pragmatic solution, that requires a single top level node for parsing?
