安装的时候显示应用未安装该怎么？

以手机为例，其安装应用显示未安装的原因如下：

1、可能是安装包在下载时不小心损坏，这样就无法进行正常森喊弯的安装，建议重新下载安装包。

2、可能渗老是手机设置没有打开“未知来源”设置，这样手机会自动无法安装第三方软件。

3、可能是手机本身的内存不够安装包进行正常的运行，没有空间安装软件了，建议安装360手机卫士，使用“清理加速”功能腾出手机内存空间或将安装在手机内存的软件搬到SD卡里。

4、可能是手机中病毒，可以使用360手机卫士进行查杀，将病毒清除。

5、重启手机或者把内存卡拔出来再安装看看。

6、此闷可能手机系统需要更新，旧的系统和软件不兼容，无法进行正常应用程序的安装。

区别就是一个需要安装，一个不需要安装！:51

有些（游戏）软件可以不安装运行。而需要安装的或必须安装梁清租的软件，不管你安装在那个分区都会向c盘或注册表写入文件，并关联这些文件和部分系统文件，否则会或轻或重的影响橡兆该软件的启动正型运行。

可以用注册表编饥含辑器修改配置，先新建文本文档，把复制下面的注册表代码粘贴进去，保存后，后缀改为reg，右键用管理员权烂旁笑限打开菜单就可以了
