I am currently running Enthought Canopy version 1.5.2 full version, through an academic license at a 64bit Windows 7. I was a happy user for a couple months until a 'pythonw.exe has stopped working' issue rendered the software useless. This issue shows up when I open the editor (Ipython+Canopy's GUI) and does not allows me to use the software at all. I have tried the following solutions without luck:
Fresh install deleting several folders manually (https://support.enthought.com/hc/en-us/articles/204469700-Uninstalling-and-resetting-Canopy)
Fresh install+clearing python registry keys under hkeys_user and hkey_system and pythonw.exe related keys into windows regedit.exe (Problems in fully uninstalling Python 2.7 from Windows 7)
My second try actually gave me a false sense of victory, when Canopy worked for a couple hours, until the same issue happened taking all hope with it.
I don't know what to do anymore, any help would be much appreciated.
I had this problem also. And discovered it was due to my windows firewall blocking pythonw.exe
Either turn off the firewall. Or create exceptions for pythonw.exe (but be warned this files occurs in a few different directories. And I'm not sure which one gave the specific issue.
In the end I installed a new firewall (COMODO). And now everything works...
I followed the directions to build, install, and run Open webOS simulator for Ubuntu 12.04. Unfortunately, when the display comes up, following ./run-luna-sysmgr.sh, most of the webOS desktop is hidden (see image below). The images I've seen of a successful install show the entire desktop displayed and filling the entire application window.
I've verified all of the dependencies in the instructions and repeated the build and install steps a few times, but the results are the same. I also tried searching through the Open webOS website and Google, but was unable to find anything related to this particular problem. I even watched a few YouTube videos of the entire build, install, and run process from beginning to end. I still could not identify any issues with my own process.
I ran into the same problem. Switching from 64-bit Ubuntu to 32-bit fixed it for me.
I used the online download of Qt to install it on my desktop but now I also want it on my laptop and I am unsure of how I can do that without having to re-download. My internet connection is crap and I don't even know if the Laptop will allow me to considering that it is one issued by my school and not all downloads work. Please help! I tried copying all the files over to the laptop but now all the settings are weird because the computer I am using doesnt have (or allow access) to the C drive.
I've looked at where does an installed version of Qt store the paths.
It seems that you need to change the following:
Qt5.2.1/5.2.1/[compiler]/mkspecs/modules/qt_lib_[module].pri
In each of those files, change the line that begins with QT.[module].rpath.

In windows 7 (64bit) windows explorer when I right clicked a Python file and selected "edit with IDLE" the editor opens properly but when I run (or f5) the Python 3.3.1 program, it fails with the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." error message. All other methods of starting IDLE for running my python 3.3.1 programs worked perfectly.
Even the "Send to" method worked but it was unacceptably clunky. I've spend four days (so far) researching this and trying various things including reinstalling Python many times.
And NO it's not the FireWall blocking it. I've tried totally turning Firewall off and it had no effect.
Here's an important clue: In the beginning I installed and configured python 3.3 64 bit and everything worked including running from "edit with IDLE" but then recently when I needed a library only available in Python 2 I installed python 2.7.4 and from that point on the stated problem began. At one point I completely removed all traces of both versions and reinstalled Python 3.3.1 64 bit. Problem remained.
Then I tried have both 32 bit versions installed but still no luck. Then at some point in my muddling around I lost the option to "edit with IDLE" and spent a day trying everything including editing in Regedit. No luck there either. I reinstalled Python 3.3.1 still no "edit with IDLE" then Finally I uninstalled all versions of Python and I removed python references to environment variables PATH and PYTHONPATH. Then I Deleted all the Python related keys in the windows registry, deleted the C:\python33 directory that the uninstall didn't bother to delete. Overkill, of course, then I restarted windows and installed Python 3.3.1 64 bit version again and thankfully the option to 'edit with IDLE' was back. I was momentarily happy, I opened windows explorer, right clicked on a python program, selected 'edit with IDLE' selected RUN (eyes closed) and you guessed it, same original error message "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection."
I am completely stuck on this issue and really need help. Pretty sure that you can see I and not a happy camper. And to top it all off, I guess I don't understand StackOverflow yet, I have had this plea for help up in various versions for 5 days and not one response from anyone. Believe me I've looked at every thing in stackoverflow plus other sites and I can't see the answer. Almost seems like I have to answer my own question and post it, trouble is, so far I can't.
Anyway, thanks for listening. Yes I'm pretty new to Python but I've been programming and overcoming problems for many years (too many perhaps). anyone? Not personally having someone that is familiar with Python makes this difficult, how can I get in touch with an expert in Python for a quick phone conversation?
I had this same problem today. I found another stack overflow post where someone had a tkinter.py file in the same directory as python, and they fixed it by removing that tkinter.py file. When I looked in my python directory, I realized I had created a script called random.py and put it there. I suspect that it conflicted with the normal random module in python. When I removed this file, python started working again.
So I would suggest you look in your main python directory and see if there are any .py files that you could move to different places.
I'm running Windows 7 64-bit. I saw the same errors today. I tracked down the cause for me, hopefully it'll help you. I had IDLE open in the background for days. Today I tried to run a script in IDLE, and got the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." errors. So I closed all IDLE windows, and tried to restart IDLE. That then caused the same errors to pop up, and now IDLE wouldn't open successfully.
The cause was an extra pythonw.exe process running in the background. If I open up an instance of IDLE, then open a second, the second has issues connecting, and closes. But it does not close the instances of pythonw.exe that it opened, one is left running in the background. That extra instance then prevents future attempts to open IDLE.
Opening up Task Manager and killing all pythonw.exe processes fixed IDLE, and now it functions properly on my machine (1 instance open at a time though!).
Look for files on your main python folder that you may create in names like "threading.py", "tkinter.py" and other names that overlapps with your Lib folder and move/delete them
Adding to existing answers - it is actually possible to have firewall block IDLE when not running with -n flag. I haven't used IDLE for a few months and decided to try if it works properly with newly installed python3.3 (on Linux Mint 13 x86). In between I made iptables setup much more aggressive and apparently it blocked idle-python3.3 from connecting to the Python RPC server. Sometimes it is just what the message says.
I had exactly the same issue :"IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection."
I found the answer from this stackoverflow site. I created a file named string.py and that classhed with the normal python files. I removed the string.py and everything works now. Thanks folks.
I had the same error message. Error not seen after I added all the *.exe filea to be found in the Python install directory to the Windows firewall exception list.
I finally got it to work when I disabled ALL firewalls and antivirus, because some antivirus ALSO have firewall control. Ex. avast
Remove copy.py in your folder if you happen to have one
Using Windows 7 64 installation of Python 2.7.10 Shell I solved the above problem by opening the program as an administrator.
i have the Same issue on os win7 64Bit and Python 3.1 and find a workaround because i have a Project with many .py files and just one gave this error. - Workaround is to copy a working file and copy the contents from not working file to working file. (i used Another editor as idle. The Problem with that workaround is... of you rename the file it doenst work. attention just rename the not working file doesnt work for me. just that copy paste. – john
I came across this problem too. There are two things you can do
You may already have a process running call pythonw.exe which prevents IDLE from being starting. End that task and try running IDLE again
Use pythonwin or python command line
Basically, yesterday I could program in C++ and today I cannot.
I'm trying to write a simple hello world program in Eclipse Helios using the MinGW C/C++ compiler and I'm running into several problems, and I believe this one to be the root of it.
At first the program compiled and built, but when I tried to run it, an error dialogue said the FirstProject.exe file could not be found/does not exist in the launch configuration. However, I got no errors building and I could clearly see the binaries in Debug/FirstProject.exe in my project explorer. I tried refreshing my project explorer and alas, the file disappeared before my eyes.
I tried building the program again, and that's when I get this error:
c:/mingw/bin/../lib/gcc/mingw32/4.6.1/../../../../mingw32/bin/ld.exe: final link failed: No space left on device
I don't know what device it's talking about. I have more than 1TB left on this hard drive, so it can't be that. I tried emptying my %Temp% folder and recycling bin (suggestions I found trying to search for a solution for this problem) but to no avail.
It may be worth noting that C++ programs I have written in the past are still running. I'm very new to programming, so I don't know how much information you need, but I'll gladly add anything you need if you think you can help me out.
I just solved this on one of the computers at work which had the same issue when compiling through Codelite. Moving workspaces, rebooting, and reinstalling Codelite didn't fix the problem. I also checked permissions on the /temp folder which were fine.
It turns out there were permission issues/other issues with the disk. Running a disk check fixed a few issues on the disk and that allowed the program to compile. If this doesn't solve your issue you may also want to try disabling any anti-virus/spyware programs and try again.
I just solved this problem on my PC. Actually what the problem in my case was that my windows defender (or any antivirus in someone's case) was blocking ld.exe from accessing the protected folder that is the source code folder. You can correct this by going into the Virus and threat protection settings of your PC and then find there for blocked history. You will definitely find there a history record of that blockage. Then just go and allow on this device it. And boom 😁
