更换MSI内部的小文件最简单的解决方案？

我们的许多客户都可以访问InstallShield,WISE或AdminStudio.这些都不是问题.我希望有一些方法可以为我们的小客户提供免费的商业重新包装工具,这些工具和步骤可以自行更换文件.

只需要在压缩的MSI中替换单个配置文件,可以假定目标用户已经安装了Orca,知道如何使用它来自定义Property表(嵌入GPO部署的许可证详细信息)并生成MST文件.

免责声明:这与另一个问题非常相似,但该主题中的问题和答案都不清楚.

好的,用我自己的答案重新审视这个问题,提供了很好的小VB脚本,可以完成所有繁重的工作.正如原始问题中所提到的,目标是为系统管理员用户提供一个简单的解决方案来自行进行更新/更改.

以下是我目前向客户提供的代码的简化版本
