Repairing the Game Client

Repair Instructions for Windows®

If you are having problems running Guild Wars 2, the data archive may have become corrupted. Please follow these steps to verify and repair the archive:

  1. Locate your Gw2.exe file.
  2. Right-click on the file and select Create shortcut.
  3. Rename this new shortcut to Guild Wars 2 Repair.
  4. Right-click on Guild Wars 2 Repair and select Properties.
  5. Locate the Target line and add –repair to the end. (Example: “C:\Games\Guild Wars 2\gw2.exe” -repair)
  6. Click OK.


Double-clicking Guild Wars 2 Repair will begin the repairing your game client. The game will launch when it is complete.

Note: Keep in mind that the verification and repair process will run each time you double-click the Guild Wars 2 Repair shortcut. If you would like to play the game immediately without repairing the archive, double-click on Gw2.exe or another shortcut without the -repair command.

Repair Instructions for Mac:

  1. Click on the “Finder” icon located in your Dock or the desktop of your computer to make “Finder” the active program in the Finder menu bar.
  2. Click on “Go” in the Finder menu bar. A dropdown will appear.
  3. Click on "Utilities."
  4. Once in the "Utilities" folder click
  5. Copy and paste the following line into the terminal and click “Enter”: 

/Applications/Guild\ Wars\ 2\ -repair


These steps should start the repair of your client. Let the process complete and once done, close out of Terminal, log into your account, and see if the issue persists.

I moved the file "GW2.exe" to a folder and launched it, but it immediately crashed. What’s wrong?

This could be caused by a number of issues, but here are a few things to check for:

  • Are you an administrator on your computer or on Windows Vista / 7?
    • You may need administrator privileges to run the client or access the folder in which your game client is located. Try starting Gw2.exe by right-clicking on the file and selecting Run as Administrator.
  • Is the folder that contains the game set to “Read Only?”
    • The client needs to add files to the folder by updating before it will run properly. To check this, right-click on your Guild Wars 2 folder and select Properties. From here, un-check the option for “Read-Only” and left click on Ok.
  • Have you updated your video card drivers recently?
    • AMD users should be using Version 12.3 located here.
    • Nvidia users should be using Version 296.10 located here.
  • Do you have Windows 7 Service Pack 1 installed?
    • Guild Wars 2 is not supported without this service pack and in many cases we have seen the installation of this service pack resolve this issue. Please visit, choose all of the available critical updates, and install them.

My client is stuck updating at 99% with one file left. What should I do?

  • First, locate and delete your local.dat file which can be found in your Documents > Guild Wars 2 folder.
  • Next,reboot your computer and launch Guild Wars 2 again. After seeing the “1 file remaining” message, a secondary protocol should kick in to download the missing file from the backup system. This process usually takes about 10 minutes.
  • If after 15 minutes or so you find that the above process has not resolved the issue – that is, you’re still stuck at a 99% download – please try this work-around: Change the language setting for the launcher (in the top right corner of your screen) to a different language. At that time, the download should complete. Once that occurs, change the launcher back to your original language and log in to play.

I’ve downloaded the client and now must patch thousands of files. Is this normal?

Yes, this is perfectly normal. These files are the most up-to-date data and content files in the game, and are required to play Guild Wars 2.

What is a build and why do they keep interrupting the game?

A “build” is the technical term for a particular version of a game. Since Guild Wars 2 is updated frequently with new content as well as the occasional bug fix, there may be several new builds a month. Every time we distribute a new build, it automatically will exit you from the game (your progress is saved prior to exiting). All the files associated with the new build will download onto your system the next time you launch the client. In many cases you will be able to log back in to the game almost immediately, but occasionally you will need to wait a bit before rejoining the game. You can read the details of game updates on our official forums.

My client “repairs” itself every time I crash. What should I do?

The most likely possibility is that your Gw2.dat file has somehow been corrupted, either in downloading the game or due to a crash.

  • First, try re-downloading the file by renaming your current Gw2.dat to Gw2.old and running the launcher again. This will “back up” your file and allow you to download a new working copy.
  • In addition, you may want to make sure that your GW2 folder is not installed to your Program Files directory. We recommend C:\Games\GW2 or something similar.
  • If you’re still having problems, you may have hardware issues or background applications may be causing the file to become corrupt. Try our Technical Support forums for more assistance and mention the location of your GW2 folder. Alternately, you may submit a support ticket.

Note: If you receive an Error 502 when trying to access the forums, please try again later.

My client gets stuck updating at “Connecting to ArenaNet.” What do I do?

  • This issue usually is caused by your firewall, which may be blocking your ability to connect to the ArenaNet servers. We recommend disabling your firewall before launching the game to determine if this fixes the issue.
  • It is also possible that another program or security software program is interfering with the game connection. Security software programs (such as AVG, Norton, and McAfee) historically have been problematic with blocking players from connecting to our servers. Try temporarily disabling your anti-virus software and connecting again. If this works to resolve your issue, you may need to configure that software to not block Guild Wars 2 in the future. 
  • In addition, please check to make sure that you are running the installation as the administrator.

Media Center launches every time I launch Guild Wars 2; how do I stop it?

Right-click the client shortcut and select Properties in the command line. On that line, you should see -mce tagged onto the end. Remove the –mce command and left-click on apply.

A new game update just came through and now I can’t log in. What should I do?

After a game update, the server can still take a minute or two longer to complete the upload. If an update or patch just went through, please wait a few minutes and try again.

How do I adjust my game language settings?

You can configure your Guild Wars 2 text and audio language settings through the In-game options menu. To make these changes you will need to log into the game using any character. Once logged in, please do the following:

  1. Press F11 to open the General Options menu.
  2. Change the first two drop-down menus to the language of your choice.

NOTE: Each language setting displays the alternative languages in its native language. For instance, depending on the language setting, the option for English is presented as English, Anglais, Inglés, or Englisch. Selecting any of those settings will enable English text and audio and will change the options menu to English as well.

When I launch Guild Wars 2, the screen goes black but I can still hear the music. Help!

There are a number of different factors that could be causing this issue.

  • First, eliminate the possibility that your router is causing issues by bypassing the router and connecting directly to your modem via Ethernet cable. If you have a router/modem combo unit, please disable the SPI Firewall setting because this has been known to contribute to black screens.
  • If this does not resolve the issue for you, another factor to consider is your security software. As a temporary troubleshooting step, please disable any security software to see if it is interfering with the client. If this works to resolve your issue, you may need to configure that software to not block Guild Wars 2 in the future. 
  • Beyond this, if you’re still experiencing the black screen issues, please submit a Technical Support ticket for further assistance.
