I don’t know what I did, it’s always like this during installation，who can help me，Thinks a lot！
Did you download the correct version (i.e., Windows, Linux, MAC, etc.)? Which OS are you running on?
yes，the system is windows10x64。I have previously installed other versions of Python, such as 3.7.4 and 3.8.10, but now I cannot install a higher version
Which version are you attempting to download? Did you attempt to download from here:
Thinks，I found that using administrator privileges can install normally
