2. Copy the tmpLauncher File to the Minecraft Folder

  • Then open a browser.
  • Press Ctrl + V to paste and open the copied URL, and download the Minecraft launcher from that page.
  • Then drag the new MinecraftLauncher.exe to the Minecraft folder to replace the original launcher.

4. Update Java Version

Minecraft is a game that requires Java to run. As such, it might also be worth checking if your Java version is the most update one. This is how you can update Java.

  • First, press the Win key + R keyboard shortcut.
  • Enter ‘appwiz.cpl’ in Run, and press the OK button.

  • Next, input ‘Java’ in the search box to check your Java version as shown in the snapshot directly below.

  • If your version is not the latest Java 8 Update 161, select Java and press the Uninstall button to remove it.
  • Next, open this page and select to download a 32 or 64-bit Java version. You’ll need the 32-bit version for 32-bit browsers and 64-bit Java for 64-bit browsers.
  • Open your browser’s about page to check if it’s a 64 or 32-bit browser. For example, in Chrome you can click Customize Google Chrome > Help > About Google Chrome to open the tab shown directly below.

  • Open the Java setup wizard to install the latest version.

One, or more, of those fixes will probably get Minecraft up and running on your Windows desktop or laptop once more. To fix other Minecraft error messages in Windows 10 and 8, check out this article.
