尝试在 Windows 7 上安装 Python 3.8.2 时出错

Question

I am using Windows 7 64 bit and when I attempt to run the executable installer for Python 3.8.2 I get an error stating that I need to install windows service pack 1 to continue. I already have windows service pack 1 installed on this drive, I've double checked and reinstalled it but this has not fixed the issue.

This is what's in the error log:

[1B0C:1D88][2020-04-10T05:16:05]e000: KB2533623 update is required to continue.

Answer 1

I have observed that versions above 3.7.2 require more that just the SP1 update. Looking at your log files, you will find that it requires you to install the update KB2533623 . Unless you fulfill the all the prerequisites for the installation, you wouldn't be able to continue with it. Install the appropriate updates as referred to by the setup/log-file and try again.

It is probable that the Service Pack 1 update might have not installed properly into the system. You would need to retry installing the updates. I am afraid to tell you that official free support and updates to Windows 7 have been discontinued since the onset of 2020, so you might have a hard time finding the correct update.

Sometimes, the update unexpectedly fails to install properly. If nothings else works, the service pack version may be fixed through the registry, but at one's own risk as it might lead to consequences.

Handling the registry is dangerous, so proceed at your own risk.

• Open the registry editor.
• Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Windows .
• Modify the hexadecimal value of CSDVersion to 100 for SP1, 200 for SP2, and 300 to SP3.
• Restart the PC.
