我想替换msi中的单个文件。怎么做？
答案 0 :(得分：45)
使用msi2xml。
此命令提取MSI文件：
msi2xml -c OutputDir TestMSI.MSI
打开 OutputDir 并修改文件。
要重建MSI运行：
xml2msi.exe -m TestMSI.xml
您需要-m忽略修改MSI文件时失败的'MD5校验和测试'。

您需要使用MsiDB.exe（随Windows Installer SDK提供）从msi中提取CAB文件流。使用-x选项从命令行运行它，并指定cab文件的名称 - 这在msi数据库的Media表中列出。
或者，如果在VSI选项中将“Package Files as：”选项指定为“在Cabinet文件中压缩”，则可以跳过此部分，以便在构建时将cab文件从msi中删除（它将在与msi相同的目录。
解压缩后，您可以更改cab文件夹中的指定文件 - 其名称已被破坏，因此您需要找到该文件的msi名称在文件表中，然后将新文件重命名为该文件。
完成后，您可以使用-a选项使用 MsiDB实用程序将其弹回。
在使用-a添加之前，您需要将 msidb -k 用于remove the cab from the MSI。

尝试使用InstEd - http://www.instedit.com/处的安装程序编辑器。它有30天的试用期，它适用于我。您将文件解压缩到一个文件夹，编辑，重建cab，然后保存MSI。除了编辑文件之外的所有内容都在GUI中完成。
这不是一个很棒的程序，但我支付了30美元才能在MSI中快速编辑文件。
除了支付和使用该应用程序之外，我不以任何方式为InstEd或相关工作。

非常简单的示例代码，用于替换MSI中的文件。这不会将新文件/ CAB重新传输回MSI，但要求CAB与MSI位于同一目录中以便安装成功。我确信你可以稍加努力改变代码以重新输入CAB。
Const MSI_SOURCE = "application.msi"
Const FILE_REPLACE = "config.xml"
Dim filesys, installer, database, view
Dim objFile, size, result, objCab
Set filesys=CreateObject("Scripting.FileSystemObject")
Set installer = CreateObject("WindowsInstaller.Installer")
Set database = installer.OpenDatabase (MSI_SOURCE, 1)
Set objFile = filesys.GetFile(FILE_REPLACE)
size = objFile.Size
Set objCab = CreateObject("MakeCab.MakeCab.1")
objCab.CreateCab "config.cab", False, False, False
objCab.AddFile FILE_REPLACE, filesys.GetFileName(FILE_REPLACE)
objCab.CloseCab
Set view = database.OpenView ("SELECT LastSequence FROM Media WHERE DiskId = 1")
view.Execute
Set result = view.Fetch
seq = result.StringData(1) + 1 ' Sequence for new configuration file
Set view = database.OpenView ("INSERT INTO Media (DiskId, LastSequence, Cabinet) VALUES ('2', '" & seq & "', 'config.cab')")
view.Execute
Set view = database.OpenView ("UPDATE File SET FileSize = " & size & ", Sequence = " & seq & " WHERE File = '" & LCase(FILE_REPLACE) & "'")
view.Execute

此代码仅在1个文件上测试，其中名称与要替换的文件完全相同。
但它应该用C＃实现Christopher Painters答案，DTF（来自WIX）
