PyCharm not opening on Windows 10


This has been happening on and off for me for a couple of weeks now. Whenever I try to launch PyCharm from the stat menu, it almost feels like there's a 50/50 chance of the window actually popping up. Can't put my finger on it as to why it happens. I also don't necessarily see a new process show up in my Task Manager. Trying the .exe's in the bin folder has the same behavior. 

Using Windows 10, Java is up to date

Has anyone encountered something similar? 


This happens to me occasionally as well since updating to 2016.2 (from 2016.1) on two separate Windows 10 machines.

Occasionally the splash screen doesn't appear. Other times, the progress bar on the splash screen updates for a few seconds then just hangs. Eventually I just kill the pycharm.exe process and try it again and it loads ok.


The problem that I have is that I don't even see the pycharm.exe process pop up in my Task Manager. 


We need your idea.log ( for investigation. You can also upload a file via form and let us know the exact file name.


I have the same issue: Try to start Pycharm 5.0.3 on Windows 7 and the window is popping up for one second and disappears. I can't use PyCharm any more. Are there any solutions?


This worked for me:

1. Reboot your machine

2. Go into C:\Users\mschmitt\<Pycharm folder>\system\tmp

3. Delete everything in there

4. Start PyCharm


No need to reboot! (at least, not for me, so try first by just removing the tmp folder, then if it doesn't work, reboot)

Thanks a lot Mschmitt!


@Anna Morozova: I checked, and the idea.log didn't contain any new lines since it stopped working. Apparently it didn't even get to that point (and I'm in the right log because it contains the shutdown info of yesterdays' run)


This happens to me all the time. @Mschmitt's workaround has always worked for me in the past, but today, for whatever reason, I am completely locked out of PyCharm. Always happens right after an update. Is this on the radar to get fixed?

Switching to VS Code for now :/


This happened to me today out of the blue.

Deleting the tmp directory did not help.

I downloaded the latest pycharm from and re-installed it.

I had the latest version already but it was the result of multiple upgrades.

Re-installing (but keeping my settings and projects) fixed the problem.


Neither of the above tricks worked for me:

1) deleting tmp then launch or
2) uninstall then reinstall then launch with no settings imported and into a new project.

Being stuck with unresponsive PyCharm for the last 2 days.
Is it solely the Community version or the paid one too has same problems?


Hi Frederic! So you are able to start PyCharm but can't open any project right?



I have managed to pass through my hurdles by running PyCharm the first time after install as an admin.
Then everything got indexed/updated. I am now able to open my projects, load some python files and execute them.

After some further testing, I found that the old workspace.xml is making my new install become unresponsive upon opening
(pycharm windows doesn't fully redraw as it manages to only display the border then hang there).

All in all, I am back at work after a good scare.  




Deleting everything from .PyCharm*\system\tmp solved the problem. However, I have few folders (.PyCharmCE2016.3, .PyCharmCE2017.1 and .PyCharmCE2017.2) and  I'm starting PyCharm Community Edition 2017.2.2 so I had to clean up temp folder from all that PyCharm folders. If I've cleaned only the latest version it didn't work.


This problem emerges when I start PyCharm but click on Exit while it is still starting up.


I just downloaded pycharm onto my windows 10 laptop and it just will not open i gave tried uninstalling and reinstalling but it still will not work. 


Hi, same problem here. I tried deleting tmp folder and pycharm isn't running in task manager as far as I can tell. The only logs contained within the logs folder are the ones from my startup the night before.

Running Win 10, and latest version of pycharm. Any fixes for this?


I had exact the same problem with PyCharm on my Windows 10 ver 1511 (50/50 chance to start PyCharm), but after upgrading Windows 10 to ver 1607, can't run PyCharm at all.


Just an update for anybody else with the same problem, I had to do a clean uninstall/reinstall and now it's starting up without issue. Not exactly a fix for whatever caused this issue in the first place, but at least it's working.
