Question

我构建了新的程序包，并编译了新的msi。然后，我尝试更新已经安装在PC上的程序，但是最后一个msi又安装了一个程序，而不是更新旧版本

如果wxs中的ProductVersion不变，则会显示“已偿还”对话框。如果更改，它将安装程序，而不是旧的。但是，如果构建了新软件包，则msi将再安装一个程序实例

 <Product Id="*" 
          UpgradeCode="$(var.UpgradeCode)"
          Name="$(var.ProductName)"
          Version="$(var.ProductVersion)"
          Manufacturer="$(var.Manufacturer)"
          Language="1033">

    <Package InstallerVersion="405"
             Compressed="yes"
             InstallScope="perMachine"
             Languages="1033"
             Comments="Windows Installer Package"/>
    <Media Id="1" Cabinet="product.cab" EmbedCab="yes"/>

    <MajorUpgrade DowngradeErrorMessage="A newer version of $(var.ProductName) is already installed." />

    <UI Id="UserInterface">

      <Property Id="WixUI_Mode" Value="InstallDir" />
      <Property Id="DefaultUIFont" Value="WixUI_Font_Normal" />
      <Property Id="ARPNOMODIFY" Value="1" />

Answer 1

您需要实施主要升级：Unable to remove previous versions of MSI. Multiple entry's show up in control panel。

此WiX元素以最简单的形式进行了重大升级：

<MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
