已有软件A,安装在C:\Program Files (x86)\A\,版本号1.0;软件安装新版本,版本号1.2,覆盖安装后A版本号仍为1.0。 卸载安装或重启系统安装,现象依旧。已排除安装包错误或卸载不彻底,多次尝试现象依旧。给人感觉就像是浏览器的cache,无论如何刷新页面看到的都是旧内容。 但更换安装目录,例如C:\Program Files (x86)\A2\,相同的安装包则版本号和功能都变为1.2。 这个现象不止一个应用出现过,也不止我一个人遇到过。例如百度上也有人求问同样的怪异问题。 https://zhidao.baidu.com/question/440284366198790124.html
