How to suppress dialogue

I marked the following “Hidden” dialog box on WiX, but still it shows up on deletion when the files are in use:

<Dialog Id="FilesInUse" X="50" Y="50" Width="361" Height="177" Title="[ProductName] Files in Use" Hidden="yes">
  <Control Id="RetryButton" Type="PushButton" X="99" Y="150" Width="81" Height="18" Text="{\VSI_MS_Sans_Serif13.0_0_0}&amp;Try Again" TabSkip="no" Default="yes">
    <Publish Event="EndDialog" Value="Retry" />
  </Control>
  <Control Id="ContinueButton" Type="PushButton" X="186" Y="150" Width="81" Height="18" Text="{\VSI_MS_Sans_Serif13.0_0_0}&amp;Continue" TabSkip="no">
    <Publish Event="EndDialog" Value="Ignore" />
  </Control>
  <Control Id="ExitButton" Type="PushButton" X="273" Y="150" Width="81" Height="18" Text="{\VSI_MS_Sans_Serif13.0_0_0}E&amp;xit Installation" TabSkip="no" Cancel="yes">
    <Publish Event="EndDialog" Value="Exit" />
  </Control>
  <Control Id="ListFilesInUse" Type="ListBox" X="8" Y="64" Width="348" Height="62" Property="FileInUseProcess" Text="{\VSI_MS_Sans_Serif13.0_0_0}MsiFilesInUse" TabSkip="no" Sunken="yes" Sorted="yes" />
  <Control Id="InstallBodyText" Type="Text" X="6" Y="9" Width="345" Height="43" Text="{\VSI_MS_Sans_Serif13.0_0_0}The following applications are using files which the installer must update. You can either close the applications and click &quot;Try Again&quot;, or click &quot;Continue&quot; so that the installer continues the installation (a reboot may be required to replace these files on a restart)." TabSkip="yes" NoPrefix="yes">
    <Condition Action="show"><![CDATA[REMOVE=""]]></Condition>
    <Condition Action="hide"><![CDATA[REMOVE<>""]]></Condition>
  </Control>
  <Control Id="RemoveBodyText" Type="Text" X="6" Y="9" Width="345" Height="36" Text="{\VSI_MS_Sans_Serif13.0_0_0}The following applications are using files which the installer must remove. You can either close the applications and click &quot;Try Again&quot;, or click &quot;Continue&quot; so that the installer continues the installation (a reboot may be required to replace these files on a restart)." TabSkip="yes" NoPrefix="yes">
    <Condition Action="show"><![CDATA[REMOVE<>""]]></Condition>
    <Condition Action="hide"><![CDATA[REMOVE=""]]></Condition>
  </Control>
</Dialog>

How can I suppress this dialogue?

Note. This dialog box should be present, and the installer will quit error 2803: dialog view did not find a record for the dialog. I just need to somehow not display it for the user or (if possible) choose a choice for them.
