Unable to execute a quiet custom action - Error 0x80070005

In Wix 3.11, I'm trying to run a DISM command using a Quiet Execution Custom Action like this:

<SetProperty Id="CA_EnableMSMQ" Value="&quot;[System64Folder]dism&quot; /Online /NoRestart /Enable-Feature /FeatureName:MSMQ-Server /All" Sequence="execute" Before="CA_EnableMSMQ" />
<CustomAction Id="CA_EnableMSMQ" BinaryKey="WixCA" DllEntry="WixQuietExec64" Execute="deferred" Return="check" Impersonate="no"/>
<InstallExecuteSequence>
  <Custom Action="CA_EnableMSMQ" After="InstallFiles"/>
</InstallExecuteSequence>

But I get an error with not much information. As my custom action is 32-bits, perhaps it's not possible to call a 64-bits exe, so I tried to invoke a 32-bit Quiet Execution CA with the 32-bits dism.exe like this:

<SetProperty Id="CA_EnableMSMQ" Value="&quot;[SystemFolder]dism&quot; /Online /NoRestart /Enable-Feature /FeatureName:MSMQ-Server /All" Sequence="execute" Before="CA_EnableMSMQ" />
<CustomAction Id="CA_EnableMSMQ" BinaryKey="WixCA" DllEntry="WixQuietExec" Execute="deferred" Return="check" Impersonate="no"/>
<InstallExecuteSequence>
  <Custom Action="CA_EnableMSMQ" After="InstallFiles"/>
</InstallExecuteSequence>

But the problem is the same:

Executing op: CustomActionSchedule(Action=CA_EnableMSMQ,ActionType=3073,Source=BinaryData,Target=WixQuietExec,CustomActionData="C:\Windows\SysWOW64\dism" /Online /NoRestart /Enable-Feature /FeatureName:MSMQ-Server /All)

I don't know what to check. The command line works fine in a cmd prompt. Any help appreciated
