how to set registry value in wix?

Question

I am trying to set the registry value for my installation location in my WiX. I want to set the key in localmachine/software so I used the following WiX file. I am not getting any build error, everything is going right but the registry value is not set.

 <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

     <?define engage.client.app_TargetDir=$(var.engage.client.app.TargetDir)?>
     <Product Id="*" Name="EngageSetupCreator" Language="1033" Version="1.0.0.0" Manufacturer="KrimzenInc" UpgradeCode="PUT-GUID-HERE">
       <Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" InstallPrivileges="elevated" AdminImage="yes" />

       <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />

      </Feature>
     </Product>
     <Fragment>
      <SetDirectory Id="INSTALLFOLDER" Value="[WindowsVolume]Engage" />

              <RegistryValue Type='string' Name='InstallDir' Value="[INSTALLFOLDER]" Action="write" KeyPath="yes" />

             </Component>
            </Directory>
          </Directory>

On 64-bit systems, 32-bit software registry keys normally found in "HKLM\Software\ExampleSoftware" are instead found in "HKLM\Software\WOW6432Node\ExampleSoftware". Check here for more information.
