What tool did you use to find all the component registrations?

If your answer is "Registry Editor", there's no chance you found them all. 
You'll need a tool specifically designed for cleaning up MSI issues.

I don't know all the keys used. They're managed by the operating system, not by 
us.

BTW, how does the installer detect whether if another version is installed?

I upgraded to Windows 11 _and_ deleted all Python 3.10 related installations in 
regedit. Still doesn't work :(

It's not really complicated, it's just a little difficult to find the right 
files you need.

> Running from the Add Remove Programs entry prompts for admin access.

Which clearly shows it was previously installed by an admin, and so you'll need 
that to remove/repair/upgrade it properly. If you aren't an administrator on 
your machine, you'll need to find out who is and ask them to do it.

> Directly running "repair" in the rc2 installer with admin says "No Python 
> 3.10 installation was detected"

This generally means you need a different copy of the installer. There should 
only be 32-bit and 64-bit ones floating around, but it may be that you actually 
need RC1 and not RC2? They are all subtly different (most notably in their 
primary UUID ;) ) and won't repair each other (which would be an 
upgrade/downgrade, which should work when you haven't deleted all the files 
manually).

Otherwise, there used to be tools out there that could delete all the 
registrations in the Windows installer database, but I haven't had to use one 
in years and I have no idea which would work well. If you can remove all the 
registration entries (which you can't do by hand, trust me, you need a clever 
tool) then you should be able to install a new version without hitting these 
issues.

Sort of, but I expected upgrading with a new directory to work. When the first 
few times didn't work, I deleted the installation directly (should have 
uninstalled it). :(

Running from the Add Remove Programs entry prompts for admin access. (Is there 
a way to do that in Control Panel?) Directly running "repair" in the rc2 
installer with admin says "No Python 3.10 installation was detected", error 
code: 0x8007064. (Same error message & code when running 3.10 final 
installation.)

Sorry if the problem is complicated.

I'm sorry, but the option is grayed out. See attached screenshot.

Steve Dower  added the comment:

You probably need to also select the "Install for All Users" checkbox, rather 
than just updating the target path. Running as admin *technically* gives you 
the ability to write to those locations, but it also implies that nobody except 
Admin should be able to access it. Choosing the proper option should do it 
correctly.

This kind of issue can also arise when you directly delete the install, rather 
than uninstalling it. Best thing to do if you can is to run a repair through 
the Add Remove Programs entry, and then uninstall it (this is because ensurepip 
needs a working install to uninstall itself... not ideal, but that's how it was 
added). Then you should be able to do the proper install.

However, if it was previously installed for All Users, then switching the 
option in your new install might be able to handle it. Trying to upgrade from 
per-user to all users seems to hit issues sometimes.

Did you delete the old installation in the old location first?

[issue45420] Python 3.10 final installation failure

[wyz23x2]

New submission from wyz23x2 :

Hi, I've downloaded Python 3.10 final (64-bit) from python.org on October 6. 
But when I run the installer with administrator permission, it says "No Python 
3.10 installation was detected". Error code: 0x80070643. The stranger thing is 
when I run "repair" from the 3.10rc2 installer, it's the same message & code; 
but, if "modify" is run, the window is "A newer version of Python 3.10 is 
already installed", error code same. Thanks for help.
