Customize wix UI: Only keep Welcome & Browsing install directory dialog

Add following code snippet somewhere between <Product> and </Product>.

    <UI>
      <Property Id="WIXUI_INSTALLDIR" Value="INSTALLFOLDER" />
      <UIRef Id="WixUI_InstallDir"/>
      <UIRef Id="WixUI_ErrorProgressText" />

      <Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="InstallDirDlg" Order="2">1</Publish>
      <Publish Dialog="InstallDirDlg" Control="Back" Event="NewDialog" Value="WelcomeDlg" Order="2">1</Publish>
    </UI>

Please note that, if you don't specify Order property, UI will go back to LicenseDlg when you click Back button on InstallDirDlg.
