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.
However, when I'm runing the installer as an administrator, hit "customize installation", tick everything excpet "balblalblabal (this requires VS 2015 or later)", and click on "install", it tells me that :
.
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.
in the last couple of days I was developing an APP on python IDLE.
I tried to import the vlc module, when I run it I get this error:
OSError: dlopen(libvlccore.dylib, 6): image not found
I installed the module with this command: pip install python-vlc.
I hope you can help me getting it work!
Thanks in advance!

python-vlc is just Python bindings for libVLC.
Without that library, it won't do you any good, because all it does is try to load that library (a .dylib, .so, or .dll, depending on your platform) and call functions out of it.
There should be installation instructions at the wiki page linked above, but on a Mac, the easiest way is to just install the VLC player. I know that if you install it with Homebrew, you get the library, in a location that python-vlc can find. But I think even the binary installer from the front page of the main VideoLAN website will work as well.
If you're using Homebrew, you'll want to read the docs for when to search brew vs. brew cask vs. other taps,1 or search somewhere like Mac App Store for the current status. But at present, the appropriate command appears to be:
brew cask install vlc
1. Generally, anything that you'd expect to find as a double-clickable app in /Applications, as opposed to a Unix command-line tool or a support library, is going to be a cask, and therefore in the tap cask, which has special shortcuts to access it. But that's a relatively new thing, and not every recipe has been converted yet.
brew install --cask vlc
Is the latest command, and it works for me!
I have python 3.3 on my Desktop and works perfectly fine. I'm trying to install 3.5 on my main laptop I work from, but once it is "successfully installed" (the message the installer always gives me) It doesn't want to open. I get a message saying python.exe is not a valid win32 application. My OS is windows vista.
Go http://www.dependencywalker.com/ and download depends.exe. Run depends.exe and open python exe. If you are lucky it will show you missing dependencies.
Check how to install these. Or post missing dependencies in your question. Maybe someone knows which package to install.
EDIT:
Watch for yellow exclamation/question marks!
EDIT:
Based on eryksun's comment you should install the Vista package from this site: https://support.microsoft.com/en-us/kb/2999226
The problem is that that version of python won't work on your specific version of windows. You are going to have to use python 3.4 as this is the only python 3 version that will work for your os.
I tried to install Python 2.7.5-64 bit in my system. I downloaded the python-2.7.5.amd64.msi from python.org website.
I am facing the following issue while tried installing it.
When clicked on the msi file. there is a window appears saying Change/Repair/Remove

When I chose any option suddenly a window comes saying "Special Thanks to ...." and then Finish option comes

Your computer obviously thinks that that version of python is installed.
Try:
Removing everything to do with python in the control panel.(or python uninstaller in python dir?)
Re-download the installer and try again.
If this fails, I suggest you ask the python team or windows for help, as it is an error.
Having some problems with Gdal installation with python 2.7 on Windows 7 32bit. I am running MSVC 2010. I have followed the instruction from the blog website
http://cartometric.com/blog/2011/10/17/install-gdal-on-windows/
The installation is fine. At the end of it, I am able to run ogr2ogr in the MS-DOS and have gotten the similar screen as listed in the blog.
However, when I am trying to use the command "import osgeo" on the Python IDLE GUI shell. A series of error message is released, reading like the following
"DLL error:.........."
I believe that this might mean that the python binding is of wrong version. I have cleared up my installation by removing the following: Python-Gdal binding, Gdal, Python 2.7
After removing them, I have retried my installation with Python 3.2.3 instead and loaded the Gdal package and python binding accordingly. However, the same error returns.
Is there any intermediate steps that I could take to verify the installation. Any other advice I could have to have the bindings installed? Or is my reinstallation method correct?
I have tried to install FWTools too. It doesnt seem to work either. I have run the Python shell from EV-shell and type in "import osgeo". Have gotten the message "no module exist...."
Thanks
Get the precompiled gdal from here:
