Some Minecraft players get an error code 5 error message when they launch that game. The full error message states: “Mojang native launcher updater. Problem moving C:\Program Files (x86)\Minecraft\tmp\tmpLauncher.exe to MinecraftLauncher.exe with error code 5.” Consequently, the game doesn’t run when that error message pops up. These are a few resolutions for Minecraft error code 5.
Fix Minecraft error 5 on Windows 10
- Run Minecraft as Administrator

2. Copy the tmpLauncher File to the Minecraft Folder
- Some Minecraft players have fixed error code 5 by copying the tmpLauncher file to the Minecraft folder. To do that, open this folder in File Explorer: C:\Program Files (x86)\Minecraft\tmp.
- Next, right-click tmpLauncher.tmp and select Copy.

3. Update the Minecraft Launcher
Downloading a new Minecraft launcher is another fix for error code 5. You can download a new launcher from the hyperlink included in Minecraft’s Nativelog.txt file. This is how you can update the game’s launcher.
- Open the game’s Nativelog.txt file (in the Minecraft folder), and copy the hyperlink in Nativelog that includes MinecraftLauncher.exe with the Ctrl + C hotkey.
- 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.
- Right-click the old Minecraft.exe and select Delete to erase it.
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.
