I accidentally downloaded Python 3.4.2 a while back but I actually needed Python 2.7, so I deleted the 3.4.2 files and downloaded 2.7 instead. Now I need Python 3, so I tried to download it but I noticed that in the control panel in the Uninstall Programs section it tells me that the 3.4.2 from back then is still on my PC.
Every time I try to uninstall/change/repair/download a newer version I can't and it tells me
A program required to complete the installation can not be found...
I can not find any remaining files connected to any sort of Python in my PC. My operating system is Windows 10. Does someone know how to solve this?
Did you try to reinstall the version you want to delete and then uninstall it afterwards ?
Try to clean Path in environment variables see here
Just delete the old version path, looks like this: C:\Python27\;

I try installing python with
pyenv install 3.11.0
(though this happens no matter the version) on my Raspberry Pi. When the install is running, there's a 3.11.0 directory in ~/.pyenv/versions, pyenv versions recognizes it, and the installed python is actually usable, but the dir disappears after the installation process finished.
Raspberry Pi OS - Debian GNU/Linux 11 (bullseye) aarch64
Aside from one time when it errored out, this has happened every time I tried installing, including 3.11, 3.10, 3.9 and 3.8
I have tried:
Installing python 3.11, 3.10, 3.9 and 3.8, so I dont think it will work with any other version
Reinstalling pyenv and its dependencies multiple times
One possible cause of this issue is that there is a conflict between pyenv and another tool that you have installed on your Raspberry Pi. For example, if you have another version of Python installed on your system, it is possible that this version is overwriting the directories created by pyenv.
Another possible cause is a permissions issue. If the user account that you are using to install Python does not have the correct permissions to create and modify directories, this could cause the directories to be deleted after they are created.
To troubleshoot this issue, you may want to try the following steps:
Check to see if you have any other versions of Python installed on your system. If you do, try uninstalling them and then re-installing the versions of Python that you want to use with pyenv.
Check the permissions for the ~/.pyenv/versions directory. Make sure that the user account that you are using to install Python has permission to create and modify files in this directory.
Try installing a different version of Python, such as Python 3.8. This will help you determine if the issue is specific to certain versions of Python, or if it occurs with all versions.
If you are still experiencing issues, you may want to try uninstalling pyenv and then reinstalling it from scratch. This will reset the configuration of pyenv and may help resolve any underlying issues with the tool.
I installed Python on Windows 11 normally after getting the setup from python.org but, by mistake, I deleted the partition Python was installed in (it was E drive). So now, when I rerun the setup, it shows that Python is already installed.
I forced uninstall the old Python and removed all the registery keys with the help of Revo Uninstaller, but now, when I try to install Python again, it isn't installed to the specified folder and when I try to Uninstall the same via setup (after installing), this is the error I come across: https://paste.pythondiscord.com/tekopijiju
So now I want to know if there's a way to force install that Python version?
This issue has been fixed.
The Fix: I reproduced the path (The E drive) I had deleted and added the same Python folder to it and then clicked the Repair button. It automatically installed Python back to that folder and then I was able to normally uninstall it and install at another location!
My project has an python version(3.10),i want to add python (3.6) version.
i dont want to delete the old version and my pc has not enough space for virtual machine.
How can i create env?
Can anyone help? Python was first installed directly, should I install anaconda?
enter image description here
I solved the problem by downloading the anaconda promt, creating a new env from there and running the vscode from within the anaconda, when I type the python version, the version I set appears when I type it in normcal cmd, the version 3.10 appears.
If you wish to use different versions of python you can use tools such as asfd which will allow you to install as using different versions by switching in the terminal.

I plan on uninstalling and reinstalling Python to fix pip. I, however, have a lot of python files which I worked hard on and I really don't want to lose them. Would my Python files be okay if I uninstalled Python?
If you are using Linux and a distribution like Ubuntu, you will definitely break the OS. Don't do it.
Moreover, there is no evidence that your installation is broken because of Python, and you may probably not solve your problem.
Your Python files are not specially managed by Python itself. If you uninstall Python, source code files (files with the .py extension) won't be affected.
There's no harm I can see in overwriting a pip installation. So, just follow the instructions and let us know if you have further problems:
Download get-pip.py.
Run python get-pip.py and get on with the rest of your stuff.
Before uninstalling python, make sure all your python applications support the new python version.
My suggestion is to create virtual environments in your system to use multiple python versions
Try Anaconda - https://www.anaconda.com/ to create multiple virtual environments, where you can run a python version on each environment.
It depends on whether you installed the Python or it came with the OS.
If you installed Python, it’s no problem at all — your files are safe and uninstalling Python won’t touch them.
If you’re planning on uninstalling the Python that came with your OS, I’d advise not do do that — it could cause a whole lot of trouble. Instead, you could install a new version of Python into your user directory and link to it by adding its location to the PATH variable used by your shell.
I'm running Windows 7 and I currently have python 3.3 installed on my system. I need to install the python 2.7 interpreter so that I can work with some outdated code, and I don't want to uninstall Python 3.3. Does anyone know how to do this without reinstalling IDLE and duplicating the system files that python33 and python27 have in common? Thanks.
As both the python versions are installed in different folders, so you need not worry about it.
You can use set "PYTHONPATH=%PYTHONPATH%;C:\My_python_lib" command in windows to temporary change the default python version to use.
While working on the projects requiring different python, you can use virtual environment approach. The following link will help you on this topic: http://docs.python-guide.org/en/latest/dev/virtualenvs/
This is widely used concept by python developers.
just install them in different folders.
When you install python 2.7 , it will be automatically be installed in a different folder just go into that folder and run python idle from there.
