我有一个包含非压缩文件的安装包。

<DirectoryRef Id="INSTALLLOCATION">
  <Component Id="LocationConfig">
    <File Id="LocationConfigFile" 
          Source="LooseFile.Config" 
          DiskId="2" 
          Vital="no" 
          Compressed="no" />
  </Component>
</DirectoryRef>

松散此文件的目的是为了在安装前对其进行编辑。这可以按需要工作。

我有一个刻录链，指定松散文件作为引导程序旁边的松散文件包含在内。还要注意使用SuppressLooseFilePayloadGeneration允许手动将文件指定为松散的有效负载。

<Chain>
  <MsiPackage SourceFile="MyInstaller.msi" 
              Visible="yes" 
              Vital="no"
              SuppressLooseFilePayloadGeneration="yes">
    <Payload Compressed="no" SourceFile="LooseFile.Config" />
  </MsiPackage>
</Chain>

刻录日志如下所示：

好的，由于文件已更改，哈希失败。但是...我想允许用户更改文件。我可以很容易地使用标准安装程序包做到这一点，那么我必须跳过哪些箍才能让它与引导程序一起运行？

I found this discussion in the WiX users mailing list. Robs response of "It should just work" sounds promising, but then the discussion seems to move on to suggest it could be a bug? If the author ever raised a bug report, I can't find it.

An alternative I considered was to exclude the file altogether from the bootstrap payload, and then manually copy it over to the MSI cache path during install so the MSI can find it, though burn will never try to validate it. But the two troubles I see there are:

  1. I can't find out how to discover the cache path from within my bootstrapper.
  2. Even if I knew the path, I'd need to elevate the bootstrapper to copy the file. That may not be a showstopper, but I have a sneaking suspicion it might prove difficult.

This isn't supported today. Burn validates everything before placing it in the cache for security reasons. What you could do is read the external file in a custom Bootstrapper Application and store the results as persisted Variables. This will be more work but Burn just won't trust files that don't match the security hashes/signatures inserted at build time.

I worked around this same issue by hanging off the current directory property that the burn bootstrapper sets and using it with a copyfile element like so:

  <Component Id="SettingsFile" Guid="...">
    <CopyFile Id="Copy" Delete="no" DestinationDirectory="INSTALLFOLDER" SourceName="LooseSettings.xml" SourceProperty="CURRENTDIRECTORY" />
    <RemoveFile Id="Remove" On="uninstall" Directory="INSTALLFOLDER" Name="LooseSettings.xml" />
  </Component>

There are quite possibly some issues with it but I'm writing an installer to someone else's specs and it seems to work
