Hi David,
Thanks for the information. I'm writing the registry data to
HKLM\Software\Classes since the is a per machine installer.
Thanks a lot,

Dear All,
I have an x86 installer which needs to create a registry key under
HKEY_CLASSES_ROOT\Wow6432Node on 64-bit machines. I created a component to do
the task. The component installs fine but does not create the key on x64
systems. Is there a way to accomplish this with WiX? Your help
32 bit (x86) installers can indeed write to wow6432nodes and do so by by
default.
Specify the key you wish to write to and omit Wow6432Node as they will be
redirected there automatically.

Its also worth noting that Microsoft say
If you run a 32-bit MSI then its registry entries will be created under
Wow6432Node automatically on 64-bit versions of Windows. This is an feature of
how Windows emulates the 32-bit environment on 64-bit Windows, nothing to do
with WiX or Windows Installer.

Hi David,
Thank you for the information. Below is my component definition:
Component Id=ClientOnlyInstallRegistryData

Are you certain you are creating an x86 msi package?
Are you using a 32-bit process to view the contents of the registry? If yes,
then the location looks exactly as it should.
If you are certain that you are using a 64-bit process to view the contents of
the registry then I would revisit the
Hi Edwin,
1. This is an x86 installer because it works on both x86 and x64 machines.
2. I was viewing the Registry on a x64 machine using Regedit.exe, and inside
the Registry I could see HKLM\SOFTWARE\Wow6432Node. Is this enough to say that
I was viewing the Registry using a 64-bit process?
You already have enough information. You need to check the what kind of package
it is (check the Summary Information Stream). It is easy for anybody with
administrative privileges to create HKLM:\SOFTWARE\Wow6432Node, even on an
32-bit system.
That said, I think you are looking in the wrong
and running Regedit is not always going to give you the right answer
because you run under your user account (a merge of other keys) giving you a
virtual view of the registry for your account, which is David Watson's comment
about is bad form to actually write to HKCR directly (its
