当我尝试安装 Microsoft Teams 或任何其他应用程序时，我得到了Installation has failed。检查安装日志时，我得到了

此外，当我尝试从桌面或主菜单中的快捷方式打开其他已安装的应用程序（如 Discord）时，它们无法打开。我检查了快捷方式是否用于update.exe文件，即使我尝试从那里启动，该文件也无法打开，但当我尝试打开名为 app 和 Discord 的应用程序时，它们都可以正常工作
这个问题是怎么产生的，又该如何解决呢？
答案1
您最近安装了 Windows 吗？做过任何疯狂的调整吗？
看起来，可能是你的防病毒软件阻止了一些“松鼠”东西的工作（https://discuss.atom.io/t/windows-10-installation-has-failed-error/19833/14），暂时禁用您的防病毒软件。
搜索“squirrel windows 10”会得到一大堆关于 Avast 的信息，您使用 Avast 吗？这可能是导致问题的原因。
