Sorry, you've reported a range of issues here and it's not clear what the 
problem is.

Many many people (literally millions) have successfully installed Python on 
Windows with these installers, and even more (including most Microsoft 
products) use the installer toolkit that we use. Fundamentally, it works 
correctly. Most issues are due to problems or configuration settings on the 
target machine.

The installer file registration is handled by Windows, and is not ours to 
manage. If the OS is choosing to leave them there after removing the files, 
you'll have to report it to them.

Perhaps you could reproduce the issue, and then send all the Python log files 
from your %TEMP% directory? That should show us why your install is failing.

[issue44372] Can't install Python3.8, 3.9, 3.10 various errors including 0x80070643

[Thomas Schweikle]

New submission from Thomas Schweikle :

Python Setup for python-3.8.10-amd64.exe, python-3.9.5-amd64.exe, 
python10.0b2-amd64.exe fails after exausting "No Python 3.8 installation was 
detected.", then again "No Python 3.8 installation was detected." next it tells 
about "Error 0x80070643 while installing".

Non of the workarounds you'll able to find will work.

Looking into the registry you'll find various entries like:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components\0255A3B1CB3E0445EBD928E5D9ABECFD]
"8400E080C358BF9469DE03ED7FBAE643"="C:\\Program 
Files\\Python\\38\\Lib\\lib2to3\\fixes\\fix_funcattrs.py"

I could find ~300 entries for Python 3.8, ~400 entries for Python 3.9 and ~1000 
entries for Python 3.10.

I've installed into a new windows 10, then removed Python 3.8 looked into the 
registry and found -- nothing. Tried the same, but this time installed Python 
3.8 and Python 3.9 in parallel before removing Python 3.8 and then Python 3.9. 
Again nothing. Next try: installed Python 3.8.9, then Python 3.9.0. Next 
upgraded Python 3.8.9 to 3.8.10. Then upgraded Python 3.9.0 to 3.9.5. Then 
removed Python 3.8.10 and Python 3.9.5. Voila! Lots of entries!

Conclusion: the installer does what it is expected to do, as long as you 
install and then remove the same version. As soon, as you upgraded in between, 
then remove it will leave various entries in the registry behind and 
reinstalling will fail with error 0x80070643.

Your installer has to do its work different: do not upgrade an existing 
installation "in line", but backup necessary parts, then remove the existing 
installation, clean up registry, then install the new version, restore what you 
backed up before.
Seems the installer looses track of these registry entries if upgrades are done 
inline and later on these existing entries make reinstalling/upgrading 
impossible.
