WiX installer not removing files on uninstall

Question

I am telling a wix MSI file to remove files on uninstall, and it's simply not registering it.

For the bundle I call the MSI file thusly:

<MsiPackage SourceFile="..\..\..\..\Kiosk\MyProject\bin\Release\MyProject.msi"        Name="MyProject.msi" DisplayInternalUI="yes" Permanent="no" />

And in the MSI file I call this:

<ComponentGroup Id="Purge" Directory="INSTALLFOLDER">
  <Component Id="PurgeFiles" Guid="">
    <RemoveFile Id="RemoveBaseFolder" Name="*" On="uninstall" Directory="INSTALLFOLDER" />
    <RemoveFile Id="RemoveLanguage_af" Directory="Language_af" Name="*.*" On="uninstall"/>
    <RemoveFile Id="RemoveLanguage_de" Name="*.*" On="uninstall" Directory="Language_de"/>
    <RemoveFile Id="RemoveLanguage_es" Name="*.*" On="uninstall" Directory="Language_es"/>
    <RemoveFile Id="RemoveLanguage_fr" Name="*.*" On="uninstall" Directory="Language_fr"/>
    <RemoveFile Id="RemoveLanguage_it" Name="*.*" On="uninstall" Directory="Language_it"/>
    <RemoveFile Id="RemoveLanguage_ja" Name="*.*" On="uninstall" Directory="Language_ja"/>
    <RemoveFile Id="RemoveLanguage_ko" Name="*.*" On="uninstall" Directory="Language_ko"/>
    <RemoveFile Id="RemoveLanguage_ru" Name="*.*" On="uninstall" Directory="Language_ru"/>
    <RemoveFile Id="Removezh_CN" Name="*.*" On="uninstall" Directory="zh_CN"/>
    <RemoveFile Id="RemoveDatabase" Name="*.*" On="uninstall" Directory="Database"/>
    <RemoveFile Id="RemoveFileData" Name="*.*" On="uninstall" Directory="FileData"/>
    <RemoveFile Id="RemoveRecordingTempData" Name="*.*" On="uninstall" Directory="RecordingTempData"/>
    <RemoveFile Id="RemoveSignatureData" Name="*.*" On="uninstall" Directory="SignatureData"/>
    <RemoveFile Id="RemoveCacheUpdater" Name="*.*" On="uninstall" Directory="CacheUpdater"/>
    <RemoveFile Id="RemoveRecordingUploader" Name="*.*" On="uninstall" Directory="RecordingUploader"/>
  </Component>
</ComponentGroup>

I then reference the component group with:

<Feature Id="ProductFeature" Title="CacheUpdaterInstaller" Level="1">
<ComponentGroupRef Id="Purge"/>
</Feature>

Why are the files not being deleted? I have tried from both the burn exe file and the MSI file itself. The program installs fine, but the removal seems to not work at all.

Answer 1

SO, I found out what my issue was.

I wasn't properly adding the guids. The files and folders now properly get removed.
