如何让wix安装包，能自动卸载上一版本

回答

• 修改产品id
  Product Id="{165062EB-0BD5-4EB9-A5AE-6DDE3915C316}"
• 修改产品版本
  Version="$(var.Version)"
• 增加updatecode配置 ，保持不变
  Upgrade Id="{28B72714-3A68-4783-BEBF-5F3CBB74FD69}">

示例

<?xml version="1.0" encoding="UTF-8"?>
<?include Configuration.wxi?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">

	<Product Id="{165062EB-0BD5-4EB9-A5AE-6DDE3915C316}" Name="!(loc.ProductDisplayName)" Language="!(loc.LanguageId)" Version="$(var.Version)" Manufacturer="!(loc.Manufacturer)" UpgradeCode="{165062EB-0BD5-4EB9-A5AE-6DDE3915C314}">
		<Package InstallerVersion="200" Compressed="yes" InstallPrivileges="elevated" InstallScope="perMachine" />

		<MajorUpgrade DowngradeErrorMessage="!(loc.DowngradeErrorMessage)" />
		<MediaTemplate EmbedCab="yes" CompressionLevel="high" />

		<Upgrade Id="{28B72714-3A68-4783-BEBF-5F3CBB74FD69}">
			<UpgradeVersion OnlyDetect="no" Property="PREVIOUSFOUND" Minimum="1.0.0" IncludeMinimum="yes" Maximum="$(var.Version)" IncludeMaximum="no" />
