问题

尝试安装最新版的anconda 结果报Failed to create menus:

原因

show detail 一看是python3.9.12没安装成功，上python官网去看是python 3.9及以上版本仅支持至少Windows 8.1的系统，目前最高3.8的python是 python3.8.10

解决

所以最多只能装python3.8.8版本的anaconda，在anaconda 官网查询anaconda 对应的Python版本https://docs.anaconda.com/anaconda/reference/release-notes/：

可以看到最新3.8版本的anaconda是2021.05，我就安装这一版的anaconda，历史版本可在官网历史版本：https://repo.anaconda.com/archive/，也可以在清华源里下载，更快些：https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/，win 7 64位可直接下载：Anaconda3-2021.05-Windows-x86_64.exe

另外我看到有workaround强行装在win7上，可以自行百度。
