can't show dialog in WiX installer

Question

I'm modifying default FireBreath WiX script to show simple message after installation is complete. Because sometimes it is so quick, user doesn't get a chance to notice it.

I have this wxs file

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

                MigrateFeatures="yes" />
        </Upgrade>

            <ComponentGroupRef Id="PluginDLLGroup"/>
        </Feature>

      <UI>
        <Property Id="DefaultUIFont">DlgFont10</Property>
        <TextStyle Id="DlgFont10" FaceName="Tahoma" Size="10" />

        <Dialog Id="CompleteDlg"
            Width="370"
            Height="270"
            Title="Plugin installed">

          <Control Id="Description"
               Type="Text"
               X="50"
               Y="70"
               Width="220"
               Height="80"
               Text="Installation complete, return to web browser." />

          <Control Id="Finish"
               Type="PushButton"
               X="180"
               Y="243"
               Width="56"
               Height="17"
               Default="yes"
               Cancel="yes"
               Text="OK">

            <Publish Event="EndDialog" Value="Exit" />
          </Control>
        </Dialog>

        <InstallUISequence>
          <Show Dialog="CompleteDlg" OnExit="success" />
        </InstallUISequence>

        <AdminUISequence>
          <Show Dialog="CompleteDlg" OnExit="success" />
        </AdminUISequence>
      </UI>
    </Product>
</Wix>

but when I build it, I get these error messages
Error 2 error LGHT0204 : ICE20: Standard Dialog: 'FilesInUse' not found in Dialog table
Error 3 error LGHT0204 : ICE20: ErrorDialog Property not specified in Property table. Required property for determining the name of your ErrorDialog
Error 4 error LGHT0204 : ICE20: FatalError dialog/action not found in 'InstallUISequence' Sequence Table.
Error 5 error LGHT0204 : ICE20: FatalError dialog/action not found in 'AdminUISequence' Sequence Table.
Error 6 error LGHT0204 : ICE20: UserExit dialog/action not found in 'InstallUISequence' Sequence Table.
Error 7 error LGHT0204 : ICE20: UserExit dialog/action not found in 'AdminUISequence' Sequence Table.

I don't need any other dialogs, only this one. How to fix this? Can I just ignore these messages?

Answer 1

If a package has any dialogs, Windows Installer requires that it have a minimum set to show UI, mostly under error conditions. The ICE20 documentation has the full list.
