How to Fix Error Code 0029 in Minecraft Dungeons 2
Fix Microsoft Account linking problems by checking your Xbox identity, Steam connection, Windows gaming services and launch permissions in the right order.
Don't unlink accounts yet
A failed link makes it tempting to unlink everything and start again. That is a high-risk step for your Online Hero and rewards. Work through the ordered checks first.

Most launch-period backend login and account-linking problems were reported as handled, but the code itself has no published single cause. Do not treat 0029 as fully resolved for every player.
Quick answer
What Does Error Code 0029 Mean?
Error 0029 is currently associated with Microsoft and Xbox identity linking failures in Minecraft Dungeons II, especially on Steam. Mojang has acknowledged broader launch-period login and account-linking problems, but has not published a single official cause for code 0029 itself.
What is known
Players see 0029 while trying to connect a Microsoft Account, and the reported workarounds are concentrated in the Xbox and Steam identity chain.
What is not known
There is no official statement that 0029 means one specific thing such as an unlinked Steam account. Treat any single cause as a likely check, not a confirmed definition.

Identity chain
How PC online identity is actually built
Most players picture Steam pointing straight at the game. On PC the online identity passes through several components before the game sees a finished account link.
- Steam
- Microsoft Account
- Xbox profile / identity
- Gaming Services
- Minecraft Dungeons II
- Account link complete
A failure in any link of this chain can surface as one account-linking error, which is why the checks are ordered instead of guessed.
Account check
Are you linking the account you actually want?
Dungeons II signs in and verifies entitlement through a Microsoft Account, so the apps involved must all point at the same one.
0 of 5 checked
Account mismatch — fix the account before changing the game installation.
The Xbox App showing a signed-in account does not prove it is the right one. Confirm the gamertag, the Microsoft email and the identity that should own the link.
Ordered fixes
Work through the checks in order
Least invasive first. Stop as soon as linking completes, and use the summary at the end if it still fails.
Level 1
Check the current account-linking status
Low riskOfficialDo: If account linking is currently degraded, local changes will not help. Wait for it to recover before unlinking, repairing or reinstalling anything.
Expected: You know whether the problem can be on the service side right now.
Did Microsoft Account linking complete?
High-risk state
Wrong account linked? Stop before changing it
A link can carry your Online Hero, cross-progression, entitlements and cosmetic rewards. Guessing at an unlink can cost more than the original error.
- 1.Confirm which Microsoft Account is actually linked.
- 2.Check the current official unlink and account rules before acting.
- 3.Only change the link when you are sure which account should own it.
Do not create a second Microsoft Account to test a link. That makes the linking state harder to repair.
Do not do this yet
Steps that usually make 0029 worse
- Do not unlink your Microsoft Account as an early step.
- Do not link a random second Microsoft Account to test.
- Do not delete your Online Hero.
- Do not delete your save data.
- Do not download any third-party “0029 fix” tool.
- Do not reset Windows over an account-linking error.
Sign-in window
The sign-in window does not appear as expected
A missing, hidden or blank sign-in window is its own symptom. Diagnose the window before assuming the account is the problem.
Nothing happens
Close the game, confirm the Xbox App is signed in and Gaming Services is updated, and make sure the game is running with normal privileges. Then retry.
White or frozen window
Close the game, restart the platform clients and sign back into the intended account, then retry the link.
Window opens behind the game
Use Alt+Tab to look for the sign-in window. It can appear behind the game instead of in front of it.

Gaming Services and device credentials
Community workaround, not official Dungeons II guidance. It is most relevant when the Gaming Services sign-in window never appears.

FAQ
Error Code 0029 FAQ
Short answers to the questions this error raises most often.
What is Error Code 0029?
It is an account-linking error seen while connecting a Microsoft or Xbox identity. There is no published single official cause.
Why does 0029 appear when linking my Microsoft Account?
The link is failing somewhere in the identity chain between Steam, the Microsoft Account, the Xbox profile and Gaming Services rather than inside the game itself.
Do I need to link Steam and Xbox?
Not as a universal rule. If you play the Steam version and linking fails, checking the Steam to Xbox association is a high-value step, and it has resolved the problem for some players.
Why doesn't the Microsoft login window appear?
The window can be hidden behind the game, blocked by a stale session or interrupted by outdated gaming components. Check the sign-in window diagnostic first.
Why is the Link Microsoft Account button missing?
It sits low in Settings, so scroll fully down first. It has also disappeared temporarily and returned after a restart, so do not reinstall over it.
Should I unlink my Microsoft account?
Not as an early step. A link can carry hero progress, entitlements and rewards, so confirm the official rules before changing it.
Why do I get both 0029 and 0064?
They can appear in the same flow. Fix the account-link state first if 0029 happens during linking, then continue with 0064 if login still fails.
Does reinstalling fix 0029?
Usually not by itself. If the wrong account is linked, reinstalling does not change that. Account identity comes first and installation comes last.
