I have completely uninstalled python 3.9.0 and 3.9.1 from my windows 10 computer. But when I try to reinstall 3.9.1 it gives me the dialog that says Modify, Repair, Uninstall, like it is still installed. I have run the python uninstaller, I have also removed all registry entries for python 3.9.0 and python 3.9.1 and windows 10 still thinks python 3.9.1 is still there. Any suggestions?
That did not work. Neither has any suggestions from my google searches. I cannot install python on my windows 10 machine now at all. Guess I'm screwed from learning python.
Finally got it working again. I had to uninstall everything, then install 3.8.3, then 3.8.5, then 3.8.7 then 3.9.0, then and only then could I install 3.9.1 successfully.
I am never messing with that again!
That is not the norm.
As far as I know, Python versions are stand alone, and not dependant on other versions.
is there a way to list every file in Windows 10? if i had that situation i'd want to make such a list on external storage (USB memory stick), do a binary destruct of each partition. reinstall Windows 10 fresh, list all the files again, compare the lists. the fresh install maybe can be done on a 2nd computer so i keep the python files. then i can see what failed to be removed by the uninstall. on Ubuntu, it would be the user config files that are left behind. but i don't know if Window 10 is like that. on Ubuntu, a more extreme action is purge which also removes user config files.
For later default placement when install is in folder far away👀
C:\Users\(your name)\AppData\Local\Programs\Python\Python39
You can delete folder here,restart Pc.
If install still not work into
Regedit.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Just scroll down to find Python 3.9 on right side and delete key.
I never use the default path,so i have python 3.8 and 3.9 on a easy path.
C:\python38
C:\Python39
Can choose path when install as mention in my tutorial
