On Windows, when I try to open IDLE, “IDLE’s subprocess didn’t make the connection.” message in dialogue is shown and IDLE is not opened. What could be the solution? ![IMG_20231118_064822](https://us1.discourse-cdn.com/flex002/uploads/python1/original/2X/8/8c0c7f028a26de9ea52744b104f9ddfdd93ce9b4.jpeg) ---

Did you try reading the [link that is shown in the dialog box](https://docs.python.org/3/library/idle.html#startup-failure)? There are several suggestions there for what the problem might be. Please try to check if they apply to you; in most cases the solution should be obvious. If not, please let us know what you discovered. ---

Thanks for your suggestion, but now I’ve reinstalled Python in my system and it’s working well. If I counter same problem later, I’ll must let you know.
