这是一个可怕的错误

Installation failed with message Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Install canceled by user.
It is possible that this issue is resolved by uninstalling an existing version of the `apk` if it is present, and then re-installing.

WARNING: Uninstalling will remove the application data!

Do you want to uninstall the existing application?

与小米红米 Note 8 pro (MIUI 10.4.4), 安卓 9 -

当从Windows PC(通过USB线)连接到Vysor(2.1.2)时,收到错误消息:

"安装APK出错:失败[INSTALL_FAILED_USER_RESTRICTED]"

即使打开了“USB调试”。

因此需要以下设置-

开发人员选项(开启) USB调试(开) 通过USB安装(开启)

留下以下内容,

开启MIUI优化(开启) 通过USB验证应用程序(开启)

它很简单,在MIUI 9中。x你需要显影器设置为ON,然后

>(系统和设备部分)附加设置->开发人员选项

(调试部分)

打开“USB调试” 打开“通过USB安装”

然后在Android选择Runb应用程序,选择你的小米手机

编辑:您还需要允许从未知来源安装

设置->附加设置->开发者选项

1) Turn ON Developer Options
2) Turn ON USB Debugging
3) Turn OFF MIUI optimization
4) Turn ON Install via USB

另一个可能的原因,如果你不小心拒绝安装特定的应用程序-删除它从黑名单。

它在安全>下通过USB安装。

注意:您可能不能简单地从Security中找到它。相反,在设置搜索中搜索“USB”,或者在安全中搜索该选项。

如果你的应用程序在那里-简单地从列表中删除。如果不是,那就是别的问题了。

If above answer didn't work for you as it didn't work for me on my Xiaomi Mi5.I tried to figure out the Core reason behind it and solve it. In MIUI, in order to change "Install via USB" option, you must be connected to the internet and signed in your Mi account. Due to some reason, requests from out of the China servers are getting rejected, so I connected to one open China VPN and tried again to enable 'Install via USB' and I got success.
