I have no idea what this means. I tried to run the MCreator after downloading it, and I got 2 check marks and an X. This is my first time using this program, and I'm not sure how to fix this.

Issue comments

Go to your user folder, there is a subfolder called .mcreator. Go in it and delete a folder called gradle in it. Then run the setup again. Make sure MCreator has a reliable internet connection when running again.

It says I cannot delete the folder because it's open in another program. I don't have anything open

In such case, first, reboot the computer and then delete this folder. There is a gradle process still running in the background most likely.
