title: WiX - altering text in ExitDialog depending on result of an action after InstallFinalize
body: <p>I would like to alter text in ExitDialog depending on result of an immediate action, executed after InstallFinalize. I have tried to do this with the use of property to be set by the action (ISSUCCEEDED in the snippet below), but as I understand it, installer lost this property after the transition from server to client phase. If so, how this could be done?</p>
  
  <pre><code>&lt;!-- The MyAction sets the property ISSUCCEEDED --&gt;
  &lt;CustomAction Id="MyAction" BinaryKey="..." DllEntry="..."/&gt;
  &lt;InstallExecuteSequence&gt;
     &lt;Custom Action="MyAction" After="InstallFinalize"&gt;...&lt;/Custom&gt;
  &lt;/InstallExecuteSequence&gt;
  &lt;UI&gt;
    &lt;Dialog Id="MyExitDialog" ...&gt;
       ...
       &lt;!-- ISSUCCEEDED is lost by now --&gt;
       &lt;Control Id="C1" Type="Text" Hidden="yes" Text="!(loc.Text1)"...&gt;
          &lt;Condition Action="show"&gt;ISSUCCEEDED&lt;/Condition&gt;                    
       &lt;/Control&gt;
       &lt;Control Id="C2" Type="Text" Hidden="yes" Text="!(loc.Text2)"...&gt;
          &lt;Condition Action="show"&gt;NOT ISSUCCEEDED&lt;/Condition&gt;                    
       &lt;/Control&gt;
       ...    
    &lt;/Dialog&gt;
  &lt;/UI&gt;
  </code></pre>
