如何在wix中卸载msi安装程序时删除注册表项值？

我正在尝试用wix开发一个简单的msi安装程序。它在32位机器上成功（安装/卸载）。当我为64位计算机开发安装程序时，它正在成功安装，但在卸载时，注册表项没有从system32和systemwow64文件夹中删除，文件也没有从中删除

我使用的wix配置如下：

        <Directory Id="TARGETDIR" Name="SourceDir">
          <Directory Id="ProgramFiles64Folder" Name='PFiles'/>
          <Directory Id="SystemFolder" Name="sys32"></Directory>
          <Directory Id="System64Folder" Name="sys64"></Directory>
        </Directory>

    <DirectoryRef Id='SystemFolder'>
          <Component Id  = "Sys32Comp"
                     UninstallWhenSuperseded ="yes"
                Guid = "7E079CEA-4A90-4C27-99F1-74FD4201BF5B">
            <File
                 Id      = 'sample'
                 Name    = 'samp.dll'
                 DiskId  = '1'
                 Source  = '$(sys.CURRENTDIR)\32\samp.dll'
                 KeyPath = 'yes'/>
    <RegistryKey Action="createAndRemoveOnUninstall"
           Key="SOFTWARE\Wow6432Node\Microsoft\Cryptography\Calais\SmartCards\SCardMiniDrv"
           Root="HKLM">
              <RegistryValue Name="ATR" Type="binary" Value="3b7a9500008065a20131013d72d641" />
              <RegistryValue Name="ATRMask" Type="binary" Value="ffffffffffffffffffffffffffffff" />
            </RegistryKey>
          </Component>
        </DirectoryRef>

<DirectoryRef Id='System64Folder'>
          <Component Id  = "Sys64Comp"
                     Win64="yes"
                     UninstallWhenSuperseded ="yes"
                     Guid = "A6CA464D-5A20-47E0-9C22-2A49DD53DC1D">
        <File
             Id      = 'sample2'
             Name    = 'samp_64.dll'
             DiskId  = '1'
             Source  = '$(sys.CURRENTDIR)\64\samp64.dll'
             KeyPath = 'yes'/>
<RegistryKey Action="createAndRemoveOnUninstall"
                   Key="SOFTWARE\Microsoft\Cryptography\Calais\SmartCards\SCardMiniDrv"
                   Root="HKLM"
                      ForceDeleteOnUninstall="yes">
              <RegistryValue Name="ATR" Type="binary" Value="3b7a9500008065a20131013d72d641" />
