I've been trying to install Canopy 64-bit on a Win 7 64bit machine. I downloaded both the quick install and the academic version. They both appear to install but fail to launch. The error message is:
Unexpected error ParseError:Invalid line line "1"
I uninstall the earlier versions of Canopy, but I'm reluctant to uninstall all my Python installations. Canopy doesn't answer bug reports and I can't afford to sacrifice my entire Python build just to get the benefits of Canopy.
During installation, I am never given the option of 'run as administrator'. I install from msi files, which don't appear to have an run-as-admin option.
Does this happen to anybody else, or do I just need to give up on Enthought?
Thanks, KC
(Update below)
Solution (offline communication with OP):
Log out of Windows. Log back in. Delete this directory:
C:\Users\<your-user-name>\Appdata\Roaming\Enthought\Canopy\
and restart Canopy.
This solution is a blunt axe. More precise solution to be posted when verified.
=== Updated November 2, 2013:
Log out of Windows. Log back in. Delete this file:
C:\Users\<your-user-name>\Appdata\Roaming\Enthought\Canopy\preferences.ini
and restart Canopy.

I try to install virtualenvwrapper-win module,and do:
pip install virtualenvwrapper-win"
It showed the error in the last line:
ERROR: Could not install packages due to an EnvironmentError: [Errno 9] Bad file descriptor
I've completely reinstalled python and updated to latest versions and checked version 64 - bit.
I had the same problem with the installation of gdown package from pip.
screenshot of the error I was getting
But then, I figured out that the actual problem was with my antivirus. Try the following steps -
Open terminal with admin access.
Try disabling your antivirus.
Check Internet connection.
Try restarting your computer.
Any of the above measures should work. Mine had the problem with the antivirus.
Try using pip3 install virtualenvwrapper-win
EnvError and OSerror are brought back when python is not involved, so it is our OS that must present inconsistencies for it (in the processes for example) even if the message returned by python is earlier vague. Here's what I did for me. I just downloaded the iso of my OS, ran it to redo my system. With the option to keep my programs installed I always had the same python error so I had to separate myself from all my installed programs except my drivers and my personal files (music, videos, etc.) managed automatically by this repair mode. If not there's also the Windows Dism tool that could help, well I think, I didn't manage to use it because of its error codes that I found interminable. it allows you to repair windows system files you could know more about it and the method I used on their official website and on other third party sites. When has the cause of this problem, I think it's due to a malware that is installed on your system and that modifies the behavior of your OS, because I had unfortunately installed one on my pc the day the python error appeared. I hope I have helped. My OS is Win 8.1
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...

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,

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'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.
