救命!
我已经用WIX安装程序项目继承了一个.NET项目。他们隐式地假设在每台计算机上都安装了.NET Framework 4.5，这在大多数情况下是正确的。现在，我们添加了一些需要.NET Framework 4.7.2的功能。我想修改安装集以检查是否存在4.7.2(或更高版本)，并在必要时通过Web安装。我发现一些文档部分地回答了我的问题，但是我仍然很困惑如何入门以及如何填写具体内容。是否有完整的演示或说明？我的理解是，我需要添加一个“BootStrapper”项目。如果我随后从主安装(现有安装)中添加/引用BootStrapper项目，或者将其作为Bootstrapper项目的一部分引用(通过MsiPackage元素)，我感到困惑。另外，如何设置要检查4.7.2的内容？我发现的所有引用都是针对4.5或更早版本的，显然注册表中用于检查的位置已更改:
How do I detect what .NET Framework versions and service packs are installed?
假设我在Bootstrapper中引用我的主要安装程序，该怎么做？
这些是我为感兴趣的人找到的链接。它们都暗示了答案，但没有给出完整的答案和/或已过时。

https://www.firegiant.com/wix/tutorial/net-and-net/bootstrapping/
https://wix.ronifuchs.com/
最后，我相信我正在使用WIX Toolset v3.11。这是文件夹指示的内容(C:\ Program Files(x86)\ WiX Toolset v3.11)
我之所以这样说是因为某些引用资料是指Wix 4.0(例如:http://wixtoolset.org/releases/“/>)
谢谢!

然后在bundle.wxs中，您需要添加以下内容:
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Bundle Name="..."
Version="..."
Manufacturer="..."
UpgradeCode="..."
>
<Chain>
<!--Install .Net Framework 4.7.1-->
<PackageGroupRef Id="NetFx471Redist"/>
<!--Install Product-->
<MsiPackage

DisplayInternalUI="yes"
Compressed="yes"

Vital="yes">
</MsiPackage>
</Chain>
</Bundle>
</Wix>
