如何使用 WIX Bundle 降级应用程序? [英] How to downgrade application with WIX Bundle?

问题描述

我创建了一个 WIX 刻录设置.Bundle 链接了多个 .MSI 文件用于全局安装(所有 MSI 都支持降级).

I created a WIX Burn setup. The Bundle chained multiple .MSI files for global installation (all MSI support downgrading).

<Bundle Name="APP 4.3.0" 
    Version="4.3.0" 
    Manufacturer="Manu" 
    UpgradeCode="$(var.UpgradeCode)">

<Chain>
  <PackageGroupRef Id="VCppRedistPackage"/>
  <PackageGroupRef Id="DotNet4Package"/>

  <MsiPackage Id="CrystalReportPackage"
              SourceFile="$(var.SolutionDir)_CommonFiles\CRRuntime_32bit_13_0_9.msi"
              DownloadUrl="http://MyAppRuntime/CrystalReport_NET40/CRRuntime_32bit_13_0_9.msi"
              InstallCondition="NOT CR32VersionInstalled OR IsInstalledCRVersionOlder"
              Compressed="no"
              Permanent="yes"
              DisplayInternalUI="no" 
              Visible="yes" />

  <MsiPackage SourceFile="$(var.SolutionDir)..\OthersSetup\Setup.msi" Permanent="yes" DisplayInternalUI="no" Visible="yes" />

  <MsiPackage SourceFile="$(var.AppInstall.TargetDir)AppInstall.msi" Permanent="no" DisplayInternalUI="yes" Visible="no" />
</Chain>

出于测试原因，我真的必须允许降级.有什么解决方案或建议吗?

I really have to allow downgrading for testing reasons. Any solution or proposal ?

提前致谢

推荐答案

Burn 不允许降级 MSI 软件包.如果已经安装了较新的软件包，Burn 会继续将该软件包标记为适用，然后安装失败，因为 MSI 会阻止降级，除非 SuppressDowngradeFailure 设置为是".

Burn does not allow downgrade for MSI packages. When a newer package is already installed, Burn proceeds to mark the package as applicable and the install then fails since the MSI blocks the downgrade unless SuppressDowngradeFailure is set to "yes".
