Thanks for finding the error code, Terry.

CaptainMitsumoto, firstly sorry for the frustration. We try to make it work reliably everywhere, but there are so many variables when it comes to installation that weird things always come up.

As an alternative, you might want to try opening the Microsoft Store app and searching for one of the Python releases we publish there (probably Python 3.8 right now, or 3.9 if you want to try it out and aren't planning to install other packages). Those use a different kind of installer that is normally much more reliable.

If we're going to keep looking into the other installer that failed for you, I'm going to need the other log files that were in %TEMP%. The one that ends in "core_JustForMe" has the actual source of this error. 

However, I can tell you that the most common reason for this error code is that your virus scanner is interfering. You might have to disable it while installing.
