Go to: My Computer -> Properties and check the System Type. Your system is missing the Update for Windows 7 (KB2533623), hence in your Python installation log file it is showing detected windows 7 sp1 without kb2533625, although it should have been detected windows 7 sp1 without KB2533623, I think this is a mistake from Python developers. To install Python 3.7 or 3.8, in windows 7 operating system, you need to install Windows 7 Service Pack 1 first and then Update for Windows 7 (KB2533623) (if not installed already).
