"Unable to start Minecraft Runtime Enviroment"

Arqade Asked by Zejammydodger on December 24, 2020

A couple of days ago I tried getting on Minecraft with a friend. They were running 1.14.2, and my Minecraft was last updated to 1.14. No big deal; I’ll just create a new instance in 1.14.2.

When I did this, it said the latest version was 1.14. It said – I cannot remember how exactly – that it could not obtain versions, and on the news page it said I was offline when I clearly was not.

I decided to try and reinstall Minecraft.

So I went to the Windows uninstaller and uninstalled everything having to do with Minecraft. I then installed the Minecraft installer and installed Minecraft.
That was when I got the message “Unable to start Minecraft Runtime Environment, this is most likely caused by corruption. Please reinstall Minecraft“.

I tried using the repair function in the installer to no avail.
So I tried going into %appdata% and manually removing the .minecraft folder, and also going to Program Files (x86) and removing anything with Minecraft in its name.
Then I reinstalled the installer, and tried again, but the issue recurred.
At that point, I searched the internet for fixes, and found and tried all of the following, followed by trying the installer again:

  • Running everything as admin;
  • Removing .minecraft (despite already having done this);
  • Making sure I’d got the right version of Java;
  • Reinstalling Java;
  • Trying the older version of the launcher (when I tried this, the entire console was blank and it basically did nothing. I checked the log and everything – I’ll provide the logs at the end of this post).

System specifications:

UPDATE:
I tried installing Minecraft on my laptop from the same site, and I got the exact same issue, leading me to believe that the site I used is dodgy. I’m going to try to find the proper site and see if that works. If it does, I will post about it, and I will include the website’s address so that no one else has this issue.

One Answer

Restart your computer then start the launcher again.

I guess the installer should include a warning about unfinished installation and that a reboot is required...
