【问题描述】：
更新：发布此问题两个月后，我切换到全新安装的 Windows 10，并且能够安装正确版本的 Anaconda Python。不幸的是，答案来得太晚了，我无法测试它们。
我想从 Anaconda Python 3.5 的 32 位版本切换到 64 位版本。首先我通过“程序和功能”窗口卸载了 Anaconda，然后我下载了 Anaconda3-4.2.0-Windows-x86_64.exe 安装程序并尝试运行它。作为参考，我使用的是 64 位版本的 Windows 7。经过一些初始处理后，安装程序卡在 Execute: "C:\Users\user.name\AppData\Local\Continuum\Anaconda3\pythonw.exe" -E -s "C:\Users\user.name\AppData\Local\Continuum\Anaconda3\pkgs\.install.py" --root-prefix "C:\Users\user.name\AppData\Local\Continuum\Anaconda3" --post root
它不会抛出任何错误，它只是挂起。我让它跑了一夜，看看它是否会进一步发展，但不幸的是它仍然卡在早上的同一个地方。之后，我尝试从以前的安装中查找隐藏的 Continuum 文件并删除了这些文件 - 还从我的 PATH 变量中删除了 Anaconda。我什至尝试安装 miniconda 而不是 anaconda，但是两个安装程序都卡在了完全相同的位置。我是否在某处遗漏了导致 Anaconda 安装程序挂起的隐藏文件？
以下是安装日志的一部分，直到执行命令卡住为止。
