Does anyone know how to silently uninstall Python 2.7 - i.e. uninstall it unattended, with no need for user interaction? I need to do it as part of an uninstallation script that installs a bunch of software silently.
I've tried running msiexec with the /x and /qn flags on the msi file that was originally installed, but it fails - it just throws up the general help message, implying that I'm using invalid options.
I've done a Google search, and can find help for earlier versions - they can be uninstalled silently by running the unwise.exe that's installed with them, with the right options. But 2.7 doesn't seem to include an unwise.exe, so I can't do that.
Does anyone know how to do this?
Edit: The answer turned out to be embarrassingly simple. Those were the correct command-line options all along - it's just that the order matters. The correct command was:
msiexec /x python-2.7.3.amd64.msi /qn
The important thing was to have the /qn option after the msi file.
Edit: Ignore what I previously said, here's the solution according to the Python 2.4 Documentation:
It is not necessary to have the MSI file available for uninstallation; alternatively, the package or product code can also be specified. You can find the product code by looking at the properties of the Uninstall shortcut that Python installs in the start menu.
Hit the Windows Key, search Python Uninstall, right click it and go to Properties. The Product Key is in the Target field, you can use that to uninstall by doing:
msiexec /x {03mY-L0NG-A77-K3Y}.msi /qn

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?

If you still get an error, go manually to your folder, as per screenshot the path should be:

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'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 am trying to reinstall Python, so I go control panel > uninstall > Python 3.6.2. It succeeds, but when I try to download 3.6.*, it says that I can't download because there is already a version of Python3 installed.
I tried to clean the registry, deleted all files named "Python", but still see the error. I even deleted the path Python in PATH.
This may be a silly solution, but for me the issue was the Python Launcher still listed in the apps list after the uninstall. Uninstalled it separately, afterwards reinstalled Python without the error.
The installer/uninstaller does not do a good job of cleaning up after itself (and that's being generous). What worked for me:
Remove all python binary folders from Program Files and Users\<username>\AppData
Clean the PATH of any and all mentions of python
Search the registry in Computer\HKEY_CLASSES_ROOT\Installer\Features for any values with python, then delete the containing key. The key names are things like "03CEBFB8CC334B3148F9B330F67264A6" (that's an example, not an actual one, since the actuals I deleted)
#3 is the one that actually got it past the hurdle, but #1 and #2 should be done anyway.
My issue persisted despite all the above. If you're still having issues:
I realized the Python installer shows a log file link... wish I had noticed it sooner. Click to open that log, search for "Detected". Find all lines with "Detected related package". These lines are specifically what's tripping the installer. Notice the version numbers are higher than the version you're installing, along with the "Operation: Downgrade"s).
Once you find these GUIDs in your log, you'll need to search each of them in the registry. I use a free registry tool called Resplendence Registry Registrar Manager (I have no connection with them), which searches the registry blazingly fast and will show everywhere it finds something. But you can also just use Windows' native RegEdit, as well.
When you find one of these GUIDs in the registry, rename the key by adding an underscore to it, like below. This is the equivalent of "deleting" them -- as far as the Python installer can tell -- but without actually deleting them. You can easily revert them if needed.
Re-run the Python installer and it should now install just fine.
Delete all the files of the old version python and try to re-install to uninstall the older version you can do it from control panel
Install another version. For example, if you are installing a 64-bit installation, then try to install 32-bit.
Download zip file from below URL.
https://www.python.org/ftp/python/3.6.0/python-3.6.0-embed-amd64.zip
Copy all the contents to the python folder which is registered in the environment.
I managed to fix all this Python cringe by doing this:
Download newest version of Python for your version after the first point. In this case it's Python 3.6, so I downloaded the latest available - 3.6.8:
https://www.python.org/downloads/release/python-368/
Run it.
Check the checkbox "Add Python to Path":
Press on the Custom Installation button:
Press Next:
Install:
It should install. Now go to Control Panel\Programs\Programs and Features, press RMB and uninstall:
Now run your wanted Python 3.6.X installation again.
If it still gives you the "A newer version of the Python launcher is already installed", run the latest installer again as in all the previous steps, but instead, check the "Install for All Users" checkbox:
Then uninstall this latest version again.
And then install your wanted Python 3.6.X installation again.
I'm throwing hands in the air, personally
I had to do it just now for 3.6, 3.7, 3.8, 3.9 and 3.10 versions because I had problems with uninstalling and installing with errors "no python installation was detected" and "A newer version of the Python launcher is already installed". Why do I have all these different versions of Python? Because different programs want different versions of Python installed and refuse to work with any other(lmao).
World would be a better place without Python.
For me, the solution to the problem (a newer version of the python launcher is already installed) was to install it via the web installer from the website (https://www.python.org/downloads/windows/)
Download the Windows x86-64 web installer. The installer took for his series (3.7). Oddly enough, it worked the first time. Previously, the registry was cleaned, and the removal of possible traces of the program - all to no avail.
I am running Windows 7 64 bit and have installed easy_install. When I run easy_install from the command prompt it opens another window for the output and quickly closes before I am able to examine what has been done.
I am aware of this question but think it may have been closed prematurely as the solution that the closed ticket referred to here does not work on my system.
When I run the cmd window as Administrator and then execute (for example):
$ easy_install pip
I get the same behavior ... another cmd window flashes and then I am returned to the prompt with no output. How then do I force easy_install to output its results in the current window?
UPDATE: (additional information) This same behavior is exhibited when using pip.exe and virtualenv.exe as well. This must have something to do with how these executables are built and how they interact with windows 7 64bit.
I discovered that the issue was the version of setuptools that I was using. I had installed python-2.7.1.amd64 and then installed setuptools-0.6c12dev.win-amd64-py2.7.
In the the quest to grab a 64 bit setuptool - I failed to notice the "dev" part of the filename.
It turns out when I uninstalled it and then installed setuptools-0.6c11.win32-py2.7 all output stays in the console. There seems to be some issues with the newer "c12" version.
On a related note - this fixes the same problem with the use of pip and virtualenv as well.
Windows 7 has made user privileges a huge hassle. It's intended to protect the average user but gives developers headaches.
Run cmd.exe as Admin (right-click on the .exe and then select "Run as Administrator") and this problem should be solved.
I've also seen this happen if you install a virtualenv and then change the parent directory name. The path seems to be hardcoded in various files when you install the virtualenv, so changing anything upstream gives it fits. You can either grep/wingrep all the files that contain the path and manually update it, or do a Google search and find the "correct" way to fix the problem (I think there is one).
First try this:
Backup your Scripts\easy_install.exe to somewhere else
Go to Lib\site-packages\site-packages\distribute-0.6.13-py2.6.egg\setuptools and copy cli.exe to Scripts\, then rename it to easy_install.exe
Run and see the result.
I'm using distribute here, if you are using setuptools and the above steps doesn't work, I suggest you give distribute a try.
I had the same issue (new window behavior displayed across a number of libraries) - I believe it was the result of the compilation method used for the setuptools binary.
I had originally used the compiled binaries that were available here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/
I just had to uninstall the setuptools binary and install one available here:
http://pypi.python.org/pypi/setuptools
Presumably you'd also be able to compile your own version should you need a win64 binary.
I had such problem with pip and easy_install on Windows 7. You can just use Powershell (could be found in accessories). It works fine.
i too faced the same problem once, here is an easy and quick solution
try specifying the commands like so:
c:\python27\python.exe -m easy_install Django==1.6.5v
I'm trying to get node.js running on Windows 7. I have no experience with Linux so I've just been blindly following instructions from tutorials I've found, but I'm still unable to build node.js.
What I did:
Install Cygwin - the entirety
Attempt to build node.js
This is the error I first got:
I then followed the commands of two other similar sites and they all resulted in this error (could getting several version of node have caused me more problems? I'm completely clueless on this).
I read somewhere that the Windows version of Python could be causing the problem so I uninstalled my Python 2.7 and added C:\cygwin\bin to the PATH.
That still didn't work and I read somewhere else that I'm supposed to rebaseall so I tried that, but I also got an error for that:
That's where I'm at now. Have any steps I've taken exacerbated the situation?
Add -e '/\/sys-root\/mingw\/bin/d' at line 110 in /bin/rebaseall file.
Then re-run rebaseall -v and you shouldn't get the error anymore.
See this pretty helpful blog posting - Node on CygWin doesn't work for Node v0.2.5. Use the latest v0.4.0 version instead.
Also consider the post's recommendation of compiling against MinGW instead of in CygWin.
First of all, why did you check out such an old release v0.2.5? When I did it a few weeks ago I just took the latest and ended up with 0.5.0pre, but it would also be reasonable to specify v0.4.3. For instance, type git clone git://github.com/joyent/node.git to download node, and then:
cd node
./configure
make install
Secondly, do not rebase by running ash from the CYGWIN shell. Instead, shutdown all Cygwin processes, then use Windows explorer to open the ash.exe binary. Since I have a Windows 7 system without node.js, I decided to follow my instructions and build. Not so easy. I ran into some wierd dll issues that all went away when I ran ./rebaseall followed by ./perlrebase from the ash prompt. It seems that rebaseall is not sufficient anymore.
Thirdly, there is a message that makes it sound like you don't have a C compiler. Some googling will lead you to sites telling which Cygwin packages you need, but at minimum install the g++ compiler and that should pull in C as a dependency.
When I did this I simply ran configure and every time there was an error, installed one more Cygwin package to supply the missing piece. Even OpenSSL is available.
What I just found is remove the windows based install of Python. After uninstalling this, everything is peachy.
I like cygwin a lot -- but recent releases have become pretty unreliable. Some packages just wont build, and some "standard" apps dont work e.g. gvim's "save as" bombs out on my installation.
A possible solution would be run one of the better Linux distributions (ubuntu, fedora, suse etc.) either as a virtual machine or a dual boot setup and do the build inside linux.
