还有另一种方法可以做到这一点，虽然它有点混乱，但它比 OP 提到的两种解决方法要少。并且信用到期，这个答案几乎是100％基于这篇文章http://weblogs.sqlteam.com/mladenp/archive/2010/04/15/WiX-3-Tutorial-Custom-EULA-License-and -MSI-localization.aspx，作者 Mladen Prajdić。
以下基于 WiX 3.5。
您创建 LicenseAgreementDlg 对话框的稍微修改的副本并将其包含在您的项目中。

在您的主要 WiX 源文件中，您添加以下代码以将新对话框“修补”到对话框序列中，而不是原来的：
<Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="LicenseAgreementKludge">1</Publish>
<Publish Dialog="LicenseAgreementKludge" Control="Back" Event="NewDialog" Value="WelcomeDlg">1</Publish>
<Publish Dialog="LicenseAgreementKludge" Control="Next" Event="NewDialog" Value="InstallDirDlg">LicenseAcceptedKludge = "1"</Publish>
<Publish Dialog="InstallDirDlg" Control="Back" Event="NewDialog" Value="LicenseAgreementKludge">1</Publish>
请注意，这是基于使用 WixUI_InstallDir 对话框集合 - 对于其他集合，例如 WixUI_Mondo，您可能必须通过查看源代码来修改上述内容。
最后，在每个本地化文件中放置一行，如下所示：
<String Id="LicenseRtf">en-us\MerliniaSMSGatewayLicense.en-us.rtf</String>
<String Id="LicenseRtf">da-dk\MerliniaSMSGatewayLicense.da-dk.rtf</String>
而且，当然，您可以按照指示放置本地化的许可证文件。我将许可证文件（和本地化文件）放在子文件夹中，但这不是必需的。
就像我说的，它有点乱，但它确实有效。
