Minecraft Dungeons II Error Codes 0029, 0060 and 0064: Sign-In Fixes
Errors 0029, 0060 and 0064 appeared on launch day when the game could not verify the Microsoft account on PC. Player-reported fixes, in the order to try them.
Errors 0029, 0060 and 0064 in Minecraft Dungeons II mean the PC version could not sign in to or verify your Microsoft account. Players fixed it by updating the Xbox app and Xbox Game Bar, signing in to the Xbox app, linking Steam to the Xbox account, and not running the game as administrator. Mojang had not published an official fix on launch day.
On launch day the most common reason Minecraft Dungeons II would not start on PC was the Microsoft account. The game asks to link or verify an account when it opens; when that fails it stops with an error code. Players reported 0029 and 0064 most often, and 0060 with a "Verification Failed" message. The account sign-in was the second most common complaint in Steam's negative reviews that evening.
These fixes come from players and launch-day guides, not from Mojang or Microsoft, which had not posted an official fix by the evening of September 29. Try them in order and restart the game after each.
1. Update the Xbox app and Xbox Game Bar from the Microsoft Store. Pending updates to either were the most reported cause of the link failing.
2. Open the Xbox app and make sure you are signed in, with the same Microsoft account you use in the game.
3. On Steam, link your Steam account to your Xbox account: in the Xbox app, open your profile, then Settings, and link Steam at the bottom of the list.
4. Do not run the game as administrator. Running it elevated appears to break the Steam link and bring back error 0029; untick "Run this program as an administrator" in the executable's Compatibility properties.
5. For 0064, set Windows to sync the date and time automatically, sign out of your Microsoft account in the game and back in, and repair the Minecraft Launcher from its App settings if you play through it.
6. Check Windows Update and your graphics driver; one player's 0060 cleared after both were updated. Reinstalling the game is the last resort.
Crashes during play are a separate problem, and the first official fix for them is out: Mojang's 1.1.2.0 hotfix of October 7 fixes several client and server crashes during gameplay, a crash when leaving an online game, a crash when the Prime Enchanter's Lightning Slam lands at the same moment as a TNT explosion, and blurry visuals at Ultra graphics quality. It reached Steam first, with Windows and Xbox Series X|S to follow; if the game crashes mid-run, update before trying anything else. The hotfix notes do not mention the sign-in error codes.
Hotfix 1.1.3.0 followed on October 22 on all platforms. It fixes more gameplay crashes, improves login stability around error code CH1, and ends a hard lock in couch co-op: going back to the main menu from the Overworld could kick the second player from the party while they created or picked a Hero. Codes 0029, 0060 and 0064 are still not mentioned, so the player fixes above remain the only ones.
