First make sure you're still connected to the internet.
If you are, 99% of the time, relaunching the Updater will do the trick.
Is the issue unresolved? You can either:
- reinstall the game (without uninstalling it) after downloading the latest version from one of our websites;
- or refer to the error codes below:
Errors U04020025, U04020194 and U0402021A: The update server data appears to be out of sync
This type of error can occur if you try to launch the game when a maintenance or patch is underway (usually on Tuesdays). The error may also indicate a problem with our servers.
Please wait an hour and keep an eye on the forums. If the problem is affecting everybody, we will probably make an announcement soon.
If the problem persists despite waiting, please reinstall the game without uninstalling it first. That way, you will only reinstall missing or corrupted files.
If this does not resolve the issue, please contact our team by sending a ticket and selecting the “technical assistance” form.
Error U04020095 : An error occurred whilst writing to disk
This error might occur if you do not have the required write permissions or if there is not enough space available on your hard disk.
Usually, the Updater does not need to be run in Administrator mode.
Depending on your computer’s settings, however, the Updater may require administrator access. If this is the case, the window below will appear, and you will need to click “Yes”.
If you keep encountering the same error in spite of this, it is because you do not have the permissions required to modify the game installation folder and thus complete the update.
If you are not trying to install the game on a network disk or a full disk, please contact our team using the “technical assistance” form.
Error U04020091 : Insufficient disk space
Your hard disk does not have enough free space to continue with the installation or update of DOFUS.
The Updater may need up to three times as much space as the size of the game itself in order to carry out updates.
You will need to free up around 3GB to com
Error U04020400 : An error has occurred
Please restart the Updater. If the problem persists, you will need to contact Support.
This is a very specific error for which we will need you to provide data known as “logs”.
Then contact us, selecting the “technical assistance” form.
