WIX installing x64 component with x86 installer?

I have a WiX installer for an x86 application. However, it needs to write to the x64 region of the registry for a single component. To do this, I have something like the following

<Component Id=foo"..." Win64="yes">
  <Condition>VersionNT64</Condition>
  <RegistryValue
    Root="HKLM" Key="SOFTWARE\Microsoft\...."
    ....
</Component>

.....

<Feature Id='MyFeature' Level='0'> 
    <ComponentRef Id='foo' /> 
<Condition Level='1'>VersionNT64</Condition> 
</Feature>

This works fine when I try to run the installer on an x64 system. When I run on an x86 system(Even though I don't expect this component to be installed due to the condition), I get the following error:

SchedSecureObjectsRollback_x64 3: SchedSecureObjectsRollback 4: C:\Windows\Installer\MSIA98C.tmp 
MSI (c) (84:80) [20:31:05:701]: Font created.  Charset: Req=0, Ret=0, Font: Req=MS Shell Dlg, Ret=MS Shell Dlg

Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor. ............

If I take out the Win64 attribute, all works fine. However, I do need the Win64 attribute for x64 systems.

Any ideas would be appreciated, thanks!

The Windows Installer does not support creating an x86 package that writes to 64-bit locations. You have to make a 64-bit package. It's an age old limitation that everyone get's upset about.

Instead, you need to create a 64-bit MSI package for 64-bit stuff then you can put that into a Bundle with a 32-bit MSI package. The MsiPackage element can have an InstallCondition to determine when to install the 64-bit package.

Remove the Condition from the Feature. You already have that condition in the Component.

<Feature Id='MyFeature' Level='1'>
    <ComponentRef Id='foo' />
</Feature>

Honestly I don't know for sure that will fix the problem, but in my own Wix setup I have code that's nearly identical but I've put the Condition only in the Component, not in the Feature, and it works as I expect: installs that component & writes the Registry key only on x64, while installing everything else on x86 or x64.
