我在这件事上看到了别人的问题，但我无法让它对我有用。我正在尝试习惯Wix所以我们可以迁移我们的vdproj（我觉得我们已经向前迈出了一步，又向后退了4步......最基本的东西已经变成了Wix完全不平凡......但我确实看到了为构建安装程序提供完全成熟的声明性标记的价值。
我在SharpDevelop的wixproj中有以下wxs。
安装工程。卸载不执行任何操作，并将安装文件夹和dll保留在原位。有什么问题？

尝试更改未卸载的组件的GUID。我尝试了同样的方法，它对我有用。这可能是因为GUID已经由其他产品在注册表中注册。
原因通常是在注册表中搞乱组件引用计数 - 通常它发生在开发期间的开发框中。由于使用了SharedDllRefCount concept（传统的，非MSI引用计数），也经常会发生Installshield软件包。
一些技术细节：Change my component GUID in wix?在一个干净的虚拟测试上验证问题是否真实而不是开发盒问题。更改组件GUID可能会产生影响（修补问题等）。
确保没有其他MSI软件包保持组件安装。
具体来说，进入控制面板/程序和功能，并确保尚未安装程序的“旧”版本。
我以某种方式让我的项目处于无法卸载我的每个组件的状态。我不知道怎么做。我编写了一个程序，它将获取.wixproj文件并将所有组件GUID更改为新的GUID并解决了问题（在我手动删除文件之后）。这是基于user593287的答案。
参数应该是项目文件的路径。从命令行运行它的一个例子是：
GuidFixer.exe MyProject.csproj
using System;
using System.Collections.Generic;
using System.IO;
using System.Xml;
namespace GuidFixer
{
public class Program
{
public static void Main(string[] args)
{
string projectFileName = args[0];
string path = Path.GetDirectoryName(projectFileName);
List<string> files = new List<string>();
XmlDocument projectDocument = new XmlDocument();
projectDocument.Load(projectFileName);
XmlNamespaceManager manager = new XmlNamespaceManager(projectDocument.NameTable);
manager.AddNamespace("msbld", "http://schemas.microsoft.com/developer/msbuild/2003");
// Finds all of the files included in the project.
XmlNodeList nodes = projectDocument.SelectNodes("/msbld:Project/msbld:ItemGroup/msbld:Compile", manager);
foreach (XmlNode node in nodes)
{
string fileName = Path.Combine(path, node.Attributes["Include"].Value);
files.Add(fileName);
}
foreach (string fileName in files)
{
// Lets only do .wxs files
if (!Path.GetExtension(fileName).Equals(".wxs", StringComparison.CurrentCulture))
{
continue;
}
// This will only update files that aren't readonly, make sure
// you check out your files from source control before running.
FileAttributes attributes = File.GetAttributes(fileName);
if ((attributes & FileAttributes.ReadOnly) == FileAttributes.ReadOnly)
{
continue;
}
bool modified = false;
XmlDocument doc = new XmlDocument();
doc.PreserveWhitespace = true; // space inside tags are still lost
doc.Load(fileName);
foreach (XmlNode node in doc.GetElementsByTagName("Component"))
{
Guid guid = Guid.NewGuid();
string value = guid.ToString("B").ToUpper();
node.Attributes["Guid"].Value = value;
modified = true;
}
// Only update files that were modified, to preserve formatting.
if (modified)
{
doc.Save(fileName);
}
}
}
}
}
我做了一些修改而没有测试它，所以祝你好运，但它非常直接。
值得检查以下注册表项以查看是否列出了您的文件。这可能导致卸载程序忽略组件，因为它认为组件是共享的。
HKLM\Software\Microsoft\Windows\CurrentVersion\SharedDlls
我遇到了类似的问题，当我将所有guid转换为大写时（根据兼容性问题的某些规范中的要求），它似乎不再存在。没有在进攻中测试这是否真的是问题的解决方案。也许这与之前的答案相同。
