我在另一台 Windows 10 机器上进行了测试，得到了同样的结果
答案1
进入 Windows Defender 添加您要安装的目录，以免被扫描以管理员身份运行应安装
答案2
就我而言，我停止了 McAfee 防病毒软件/防火墙，但这没有帮助。
我所做的是将 MiKTeX 及其安装程序移动到另一个分区（而不是我的 Windows 分区），这样就解决了这个问题。
答案3
这是防病毒/防火墙阻塞问题。就我而言，我暂时停止了所有防病毒保护，然后就过去了。我之前试过好几次，但总是出错。在日志中，我收到的消息是权限被拒绝。
答案4
就我而言，问题似乎出Temp在干净的 Windows 10 安装中，由于某种原因安装程序无法访问目录。提升的命令提示符中的以下命令有所帮助（我C:\Tools\temp首先创建了目录）：
set TEMP=C:\Tools\temp
set TEMPDIR=C:\Tools\temp
set TMP=C:\Tools\temp
setup-2.9.6300-x64.exe
PS：MiKTeX Update（管理员）似乎也存在同样的问题。因此，我不得不永久更改当前用户的环境TEMP变量。TMPC:\Tools\temp
PPS：后来，新文件夹的相同问题Temp再次出现。看来可以通过清理 的内容来解决Temp。如果之后仍有被其他应用程序锁定的文件，则创建一个新Temp文件夹并指向该文件夹TEMP并设置TMP环境变量会有所帮助。
