Setting directory of ComponentGroupRef in Wix? - path

Question

I have used the Heat tool to generate a wxs file based on a folder whose contents I want to install. This gives me a large file like this:
<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Fragment>
<DirectoryRef Id="TARGETDIR">
<Directory Id="dir1FC8A0605F7DF8B33E3EECB0A1270FA2" Name="DirectoryName" />
</DirectoryRef>
</Fragment>
<Fragment>
<ComponentGroup Id="ComponentGroupId">
<Component Id="cmp1FB67A60B41F3170889B7E5739A23560" Directory="dir1FC8A0605F7DF8B33E3EECB0A1270FA2" Guid="{2DC3B790-D29C-4090-B4CF-5C27687C6ABE}">
<File Id="filF1E1262E52254B1846C7CB2393126A6F" KeyPath="yes" Source="PathToFile" />
</Component>
</ComponentGroup>
</Fragment>
</Wix>
In my main Wix file, Product.wxs, I have a feature that references the above ComponentGroup that was created by Heat. The feature looks something like this:
<Feature Id="FeatureId" Title="FeatureTitle" Level="1" AllowAdvertise="no" Absent="disallow" Description="Feature description.">
<ComponentGroupRef Id="ComponentGroupId" />
</Feature>
This is working but when I run my installer, the files within the component group are placed in the root of the C drive (i.e. C:\DirectoryName) but I would like them to go into Program Files (e.g. C:\Program Files\DirectoryName).
Any ideas?
Thanks,
Alan

You can pass the Id of the directory you want to reference to heat with the -dr argument like
heat -dr AutogeneratedComponentsDir
Or DirectoryRefId attribute if you are using the HeatDirectory task in msbuild.
Then just define the location of that directory in your main Product.wxs.
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLDIR" Name="YourProduct">
<Directory Id="AutogeneratedComponentsDir"/>
</Directory>
</Directory>
</Directory>
