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">
