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.
I'm trying to write a function in PostgreSQL on Windows with a Python script in the body and i'm running into an error message when trying to create the plpythonu extension. The command I'm running is:
CREATE EXTENSION plpythonu;
Which produces the following error message:
ERROR: could not access file "$libdir/plpython2": No such file or directory
SQL state: 58P01
I also tried running:
CREATE EXTENSION plpython3u;
which results in this error:
ERROR: could not load library "C:/Program Files (x86)/PostgreSQL/9.2/lib/plpython3.dll": The specified module could not be found.
SQL state: 58P01
The plpython3.dll file exists at this location, but apparently is missing some critical dependency. I've searched everywhere and found nothing helpful on this. I have both Python 2 and 3 installed on the machine...
The newest (9.4 or later) binary installations from EnterpriseDB contain only plpython3u.dll. In versions 9.4 to 9.6 I had to install python 3.3 to get plpython3u run.
You can check which version of Python is needed by plpython3u.dll using Dependency Walker.
A full answer can be found:
https://postgresrocks.enterprisedb.com/t5/PostgreSQL/unable-to-install-pl-python-extension/m-p/4090
It assumes you have used stackbuilder to install the edb language pack.
Do check the commands for correctness in your installation.
E.g. path to postgresql data, install path of edb and python version.
When you use depency walker (depends.exe), only pay attention to the pythonxx.dll. With older PG versions, this may or may not agree to the version installed by the EDB languages package. For version 10.7, version 3.4 Python is required. For windows, the later 3.4 Python versions do not appear to have a msi installer. You may have to install 3.4.4, or try to upgrade PG 10 to the latest version (10.11) first. This version requires python 3.7, so then you can use the EDB download.
But the python version may already exist and be found.
could not load library plpython3.dll (here on stackoverflow) was somewhat close, but did not detail the environment vars needed.
the solution proposed does not require you to change env vars permanently, which is a great help when using several python installations.
I compiled the development version of Vim with both Python 2 and Python 3 support. The output of vim --version has +python/dyn and +python3/dyn in it. I ran the configure file with
g
./configure --enable-pythoninterp --enable-python3interp --with-python-config-dir=/usr/lib64/python2.7/config --with-python3-config-dir=/usr/lib64/python3.3/config --with-x --with-features=huge
However when I run :python import sys; print(sys.version) I get
E448: Could not load library function _PyArg_Parse_SizeT
E263: Sorry, this command is disabled, the Python library could not be loaded.
Why would this be? I found out because of YouCompleteMe stating that it requires Vim compiled with 2.x support.
Thanks
I had a similar issue on my Debian box. If you're using a Debian-based system, you will not be able to load both Python libraries simultaneously. That's why when you set --enable-python-interp and --enable-python3-interp they always load with the /dyn suffix.
If your vim plugins don't need both versions, you should just pick one of the versions and stick with it. The links below provide more info.

Vim Python Support
P.S. - In case you tried this on Windows as well, loading either Python version will work, so the /dyn isn't an issue there.
I am trying to get the Xdebug vim plugin to work which depends on python. Here is my environment: Windows 7 Professional 64bit, Vim 7.3. I got everything set up for this plugin, but when I hit F5 nothing happens. I found some blogs describing some additional steps to get this working on Windows. All of them stressed making sure the correct version of Python is installed correctly. I looked at the plugin code in the debugger.vim file and close to the top it checks to see if python is available and exits if it is not. I inserted an echo command to tell me if python is not installed, and sure enough a message box pops up informing me of such. Here is the modified code:
if !has("python")
echo 'python NOT loaded'
finish
endif
According to this blog http://phphints.wordpress.com/2008/08/20/add-debug-support-to-vim/ I need to install the version of python that includes the dll vim is looking for when I run the version command from vim. Mine reports:
-DDYNAMIC_PYTHON_DLL=\"python27.dll\" -DDYNAMIC_PYTHON3_DLL=\"python31.dll\"
So I installed the 64 bit version of python 2.7.1. Same result even though python27.dll is in the System 32 folder. I also tried adding the location of python.exe to the PATH, but this did not help. I also tried installing the 64 bit version of python 3.1.3 but this did not help. Any ideas?
I made the following changes, and now python is working (The conditional echo statement is never reached). I uninstalled Vim and re-installed it. I uninstalled the 64 bit versions of Python 2.7.1 and 3.1.3. I installed the 32 bit version of python 2.7.1.
I am guessing the change that made the difference is using the 32 bit version of Python 2.7.1 since I am using the 32 bit version of Vim. What do you think(leave a comment)?
This may not be the direct solution to your problem, but you need to make sure the vim executable compiled with Python support.
You can check what options are compiled by running :version in the vim command line.
Also, as far as I know, python3 support only added after vim7.3. If you have vim7.2, your best bet is to get python 2 working.
On Dreamhost, I did the following
installed Python 2.7.1 in my ~/opt directory,
added export PATH=$HOME/opt/bin/:$PATH in my .bash_profile
verified with python --version that 2.7.1 was default
installed setuptools 0.6c11-py2.7
installed Django 1.2.4 with /path/to/python2.7 setup.py install
verified version 1.2.4 with import django and django.VERSION in python shell
wget http://wiki.dreamhost.com/django-setup.py
python2.7 django-setup.py in my site directory ("site.com")
intentionally put a syntax error in ~/site.com/project/urls.py
visited the site in web browser and the error page still says I'm using Python 2.5.2
Why does my Django refuse to use my new version of Python?
According to this, installing-django-with-python-2-5-and-not-with-the-default-version-of-python, the problem might be with mod_wsgi (or I think passenger in my case (but I don't actually know if they do the same thing)).
Should I try to compile mod_wsgi, compile passenger_wsgi, install virtualenv, all of the above, none of the above, A and C, B D and E, or something else altogether?
Maybe you can change the WSGIPythonExecutable directive in your mod_wsgi configuration?
To configure Passenger's Python interpretter, you can follow these steps.
