WiX will not add HKLM registry setting during Windows 7 install

I have written a WiX installer that works perfectly with Windows XP, but when installing to a Windows 7 box I am running into difficulty with registry entries. I need to add an HKLM entry as well as the registry entry for the program to show in the start menu. Here is the code I am using for both types of entry:

<!-- Create the registry entries for the program -->
<DirectoryRef Id="TARGETDIR">
  <Component Id="RegistryEntriesInst" Guid="...">
    <RegistryKey Root="HKLM"
                 Key="Software\$(var.Manufacturer)\$(var.ProductName)"
          Action="createAndRemoveOnUninstall">
      <RegistryValue
          Type="string"
          Name="installed"
          Value="true"
          KeyPath="yes"/>
    </RegistryKey>
  </Component>
  <Component Id="RegistryEntriesVer" Guid="...">
    <RegistryKey Root="HKLM"
                 Key="Software\$(var.Manufacturer)\$(var.ProductName)"
          Action="createAndRemoveOnUninstall">
      <RegistryValue
          Type="string"
          Name="version"
          Value="$(var.ProductVersion)"
          KeyPath="yes"/>
    </RegistryKey>
  </Component>
</DirectoryRef>

<!-- To add shortcuts to the start menu to run and uninstall the program -->
<DirectoryRef Id="ApplicationProgramsFolder">
  <Component Id="ApplicationShortcut" Guid="...">
    <Shortcut Id="ApplicationStartMenuShortcut"
              Name="$(var.ProductName)"
              Description="..."
              Target="[SERVERLOCATION]$(var.Project.TargetFileName)"
              WorkingDirectory="SERVERLOCATION"/>
    <Shortcut Id="UninstallProduct"
                  Name="Uninstall $(var.ProductName)"
                  Description="..."
                  Target="[System64Folder]msiexec.exe"
                  Arguments="/x [ProductCode]"/>
    <RemoveFolder Id="SERVERLOCATION" On="uninstall"/>
    <RegistryValue
        Root="HKCU"
        Key="Software\$(var.Manufacturer)\$(var.ProductName)"
        Name="installed"
        Type="integer"
        Value="1"
        KeyPath="yes"/>
    </Component>
</DirectoryRef>

How can I fix this problem?

On a side note, the registry permissions are the same on the Windows XP and Windows 7 computers.

I have figured out why this is happening.

With the WiX installer being compiled on a x86 platform, Windows 7 picked it up as the 32-bit installer with 32-bit registry keys. Windows 7 64-bit handles 32-bit registry entries by doing just what I saw happening.

The program was still registered; it was just not in the 64-bit portion of the registry. Compile it under a x64 platform while making the necessary changes to make it for a 64-bit system (ProgramFileFolder become ProgramFiles64Folder, etc.), and it will put things in the right place.

There are some differences to how Windows 7 handles certain registry keys. Registry reflection was removed starting with Windows 7. I am not sure if this plays into what you're seeing here, but check out this link for more on that.

Also, if you're working with a 64-bit version of Windows 7 you might be able to dig down into some specifics by referring to the MSDN 64-bit Windows Programming Guide.

Furthermore, if you need to have different registry keys installed into different locations based on the Windows flavour (XP, Vista, 7, etc.) then this Stack Overflow question also has an answer for you.
