I started to learn Python and got stuck on my own language (I'm not English Native Speaker), main user folder name was by kirilitsa.
It cause trouble with installing new elements to Python. I changed name and now console don't see Python, I tried to reinstall manual and from Control panel but still it somehow exist in my pc and I can't repair, modify or uninstall it.
I think there is a path which lead to old version of folder name but I can't even imagine where it can be.
Is there any solution or to reinstall windows will be faster?
It shows right way but...:
Changed path:
From the Official Docs.
Do this
Modifying an Existing Installation:
Re-run your installer (e.g. in Downloads, python-3.8.4.exe) and Select "Modify".
Check all the optional features you want (likely no changes), then click [Next]. Check [x] "Add Python to environment variables", and [Install].
UPDATE
NOTE:
I see that from screenshot you are installing the 64-bit Python, what version is your Window?
if is 32-bit then just go here and get the 32 bit (32 bit here)
Run Installer as Amministrator
Have Windows “Run” dialog run as Admin?
How To Run Programs As Administrator In Windows 10
If you still get an error, go manually to your folder, as per screenshot the path should be:
C:\Users\Timur\AppData\Local\Programs\Python\
Follow this instruction
How to add to the PYTHONPATH in Windows, so it finds my modules/packages?
Add
C:\Users\Timur\AppData\Local\Programs\Python\Python39\
And
C:\Users\Timur\AppData\Local\Programs\Python\Python39\Scripts\
5 months later I'm found how to fix the problem.
After several wrong deletion of Python 3.9.1 which screwd up things there still was some in system installer, like this but 3.9.1 version:
You need to kill them all before u could install new version or update. Good proggram which I used: Reg Organizer.
Install it, open important sections registry, find all python 3.9.1 or version you have problem with and delete:
Done! Worked with me.
I too deleted python by mistake and found that I was unable to uninstall or reinstall. When I launched the python installer, the only options I could choose from were - Modify, Repair, Uninstall. Neither modify nor uninstall worked since I got the same message 'No Python 3.9 installation was detected'.
It was perfectly solved using Repair option. I then chose to uninstall completely and reinstall. It would probably also be a good idea to check the environment variable 'Path' and also Registry Editor to make sure there is nothing left over from the previous installation.
I need some help with installation of FontForge Python on Windows.
I am trying to get ffpython to be usable across the whole system by
adding appropriate entried from fontforge-console.bat
redirecting the Python Path to FontForge installation path
The console said that Python is missing .dll files and I do not know what happened.
I tried searching for installation that comes with Python installation and came up nothing. THe documentations are too old and didn't give enough information to build my own. Current version is 2019-08-01 on Windows 10 1909. Please give any pointers on how to install FontFoge Python module.
I have uninstalled Python and now I cant install it anymore (error 0x800705b4). Has anybody encountered this error ? I have tried different versions but nothing works.
You can try Anaconda for Windows which has seperate environments.
The solution I would recommend though is to use WinPython, which after install is just a folder with everything you need, doesn't change a thing in your windows environment and still works great! There is also a version that comes with the most used packages already installed, give it a try!
No need to mess with environments, just use a different WinPython folder for your projects!
Got the same error after a little digging I found the below thing...It works like a charm...
First...Make sure to check the setup package for your system which is X86 or x64, download packages based on the system before you proceed, otherwise, the hack won't work. The below is explained for x64 bit windows 8.1 system with a 64 bit Python setup package use the below-mentioned setup name(.exe file) in Step1: and search in google for downloading the Python setup
Start CMD as Admin, after that
Step1: ~YourFilePath/python-3.5.0-amd64.exe /quiet InstallAllUsers=1 PrependPath=1 Include_test=0
Step2:
~YourFilePath/python-3.5.0-amd64.exe
~YourFilePath stands for the location of the python-3.5.0-amd64.exe file on your PC Example: E:\Softwares\python-3.5.0-amd64.exe
now after executing Step2: the setup will run without any errors..... Cool...
The above-mentioned steps should work or else If you find any difficulties please visit here which explains the process in detail. Good Luck...

Eventually what did the trick for me was to roll back the previous microsoft update (KB4512575)
I'm actually using Python for an audio steganography project but I have some troubles.
I searched this error code on the forum, but I found things about SQL installations and not Python.
I'm trying to re-install Python 3.6.5 after an uninstall, because of a bug with pip.
I installed Python 2.7, Python 3.6.5, Python with VS 2017, before uninstall it because it wasn't working.

I realy need Python to work and I'm now stuck ...
If anybody here could help me, it would be nice !
Thanks all,
maleik.
PS : I have the log for you :*
The log link
I found this in the log file which you have attached. Try cleaning the registry with CC cleaner and give it a try. If it still doesn't work, try installing python with web installer Python Web Installed 3.6.5.

I installed python from Microsoft store after facing this problem and it magically got installed without any error as it may have directly been installed. I don't know but try if it eorks for you too.
You need to run the installation as a local administrator.
I had the same problem installing Python version 3.9 for the first time on my Windows 10, as this same problem happens to many users trying to install Python, the best solution I accidentally, just like #MANAN AGGARWAL discovered trying to check if I already had a version of Python installed on my computer by the DOS Command Prompt, was:
Open the DOS Command Prompt (cmd) and dictate "python": if a screen shows you a version, it's clearly not the first time you've installed Python, so if you want to upgrade you should try: https: / /www.delftstack.com/en/howto/python/how-to-update-python/ But if you've never installed any version of Python, the solution lies in updating your operating system to the latest version through Windows Update, and open the command prompt and type Python, or go directly to the Microsoft Store and search for Python followed by its latest version. It works without error.
** If by chance it does not automatically install on your PC after downloading, click "install on my devices" and select your computer name.
Why can't I install Python directly from the website file? Please note that when trying to install any software/applications from outside Microsoft's trusted locations, there are high chances of user settings interfering with the installation. When coming, for example, from the Microsoft Store, a chance of success is much greater, even without having problems related to User Permission Settings.
Another important thing to point out here is that installing a lot of software from outside Microsoft's trusted platforms can cause you to change some user permissions which can have positive effects with some software and negative effects with others, even with security your own system if you don't know what you're doing.
it's simple , Try Lower Version Like 'Python 3.6' but Download web install.
install it , then install last python version.
your python will update.
I've faced same/similar problem with installing Python 3.9.12 in a clean Windows 8.1 64-bit (VirtualBoxed test environment).
I thought the issue could have been fixed in a newer version of Python, but the freshest 3.10.10 fails with same issue.
The original log isn't available any longer, but luckily it is quoted in another answer, and the following line reveals the real problem:
Applied execute package: core_AllUsers, result: 0x80070643, restart: None
My log looks the same, and if you scroll the log up, you'll discover that core_AllUsers is a UCRT MSI-installer, which is downloaded from Python site (for 3.10.10 64-bit the link may look like https://www.python.org/ftp/python/3.10.10/amd64/ucrt.msi).
If you download it manually (Python installer is smart enough to do a cleanup even if it fails, so you won't find this MSI in a local cache) and run, it will probably crash. And if it is your case, I have a simple solution - just install update KB2999226 (Update for Universal C Runtime) for your OS, which you can download from Microsoft.
I also faced the similar issue. What the trick worked for me is I installed it for the individual user (as earlier installation was for the all users).
So earlier if one has installed it for the all users then install it for the specific user and vice versa.
I know this is not the resolution of the error faced. However, this approach will install Python which is the main motive to achieve.
I encountered the same issue after installing a fresh Windows 8.1 on my PC.
I solved that by using the Python v3.9 web installation file which you can find here.
However, you can choose any other version that has a web installation file
Note: You need internet connection to use this method.
I've got Python 2.7 (64-bit) installed and I'm trying to install crc16. I downloaded the relevant crc16 Python 2.7 installation file:
https://pypi.python.org/pypi/crc16/0.1.1#downloads
When I try and install it, however, it says that I don't have Python 2.7 installed and it doesn't see it in the registry. Looking in my C drive I can see that I absolutely have a folder for Python2.7. Am I having this issue because crc16 is 32-bit? How can I get crc16 to install correctly?
It seems that I missed the part where it had to be compiled. It looks like the developer only made a 32 bit version for Windows. You could try using a 32 bit version of Python
Most likely you need to add the location of the Python executable to your PATH environment variable.
Right click My computer and go to properties
Click Advanced System Settings.
Click Environment Variables.
Append ;C:\python27 to the Path variable.
Restart Command Prompt.
This is based on the answer from Adding Python Path on Windows 7
