Warnings

This game requires a constant internet connection for all game modes.

Diablo III is a singleplayer and multiplayer bird's-eye view ARPG game in the Diablo series.

The game continues to receive frequent content, balance, and quality-of-life updates, including live service features like Seasons. In early 2014, Auction House which was advertised prominently on the physical copies of the game was shutdown due to negative player feedback and developer review.

Issues unresolved

Window Unresponsive

Game client window becomes unresponsive when a dialog box is opened in the background.

Issues fixed

Video Card Not Supported

Unsupported video card error.

Demo version of Swiftshader, on Intel G41.

The game may display the following error message: We have detected that your video card is not supported by Diablo III.

Diablo III will block certain systems running the game if it does not detect a certain spec of video card. However, it is possible to force the game to run on any video card (even if it does not meet the minimum specification of the game).

This fix has been acknowledged by Blizzard, but comes with its own warning from Omrakos:

...if you decide to do this and have terrible performance as expected, please do not contact us reporting it. We know the unsupported cards aren't going to perform well and there's nothing we'll be able to do to remedy it.

Method 1 - Press Esc[citation needed]
Pressing Esc instead of cancel will make one's computer attempt to load the client. Pressing cancel will load up a list of unsupported video cards on Blizzard's website.

Method 2 - Edit D3Prefs.txt[citation needed]
Go to %USERPROFILE%\Documents\Diablo III. Open D3Prefs.txt. Change HardwareClass "0" to HardwareClass "1" Change DisableTrilinearFiltering "0" to DisableTrilinearFiltering "1" Save the changes.

Method 3 - Swiftshader

Method - Swiftshader[citation needed]
Using the program Swiftshader can successfully load the game even on extremely low powered machines. For example, the game can be run on integrated graphics as low powered as the Intel G41, albeit at extremely low frame rate.

High DPI Setting

Disable DPI scaling settings.

By default, it appears as if Diablo III has a number of issues with high or custom DPI settings in Windows.

This can result in:

• Mouse cursor not being moveable whilst in fullscreen mode.
• Mouse being imprecise on the screen.
• Taskbar showing over the game window.

Disable display scaling on high DPI settings in the compatibility settings of Diablo III.exe

Login Errors

These messages may appear when trying to log in.

Error 12

This means that no license is attached to the Battle.net account, a problem with many users in Asia. Check this thread for more information.

Error 37

This message means that the login servers are at full capacity. Official advice is to try logging in later when the servers are less busy.

Error 37 workaround
Enter password. Press ↵ Enter. Press cancel before anything happens. Log back in straight away. Notes This might be considered an exploit of the way that the client is reporting Error 37 to indicate that servers are too busy. However, this does not seem to have any particular consequences, except that Blizzard's servers will be busy.

Error 75

Error 75 means that Blizzard servers are down. Check Diablo III support page for updates in the header.

Can't Move Mouse In Fullscreen

Disable DPI scaling settings.

This is most likely caused by high or custom DPI settings in Windows.

Method 1 - Compatibility

Method 1 - Disable display scaling on high DPI settings in the compatibility settings of Diablo III.exe

Method 2 - Edit D3Prefs.txt To Windowed

Method 2 - Edit D3Prefs.txt[citation needed]
If one is stuck in fullscreen mode, one can change the D3Prefs.txt settings to force a windowed mode. Open %USERPROFILE%\Documents\Diablo III\D3Prefs.txt in a text editor. Change the DisplayModeWindowMode value from "0" to "1" (with quotation marks).

No Diablo III License Attached

This error message may appear:

|This Battle.net account does not have a Diablo III License attached to it.

Correctly set the region within the game settings, within the Options > Account > Server Region settings.

Overlays

Running programs that put an overlay over Diablo III (such as Mumble and MSI Afterburner) can cause Diablo III to crash. Use these overlays at your own risk.

Problems with Steam overlay

Problems with Steam overlay[citation needed]
Add DiabloIII.exe with the "+ Add a game" option. Right-click Diablo III in the library and choose Properties Add -launch to the end of the target. If the game does not launch correctly, make sure the Battle.net Launcher application is already running before starting the game from Steam.

Cinematics not playing or are missing from cinematics menu

Edit configuration file
1. Go to %USERPROFILE%\Documents\Diablo III. 2. Open D3Prefs.txt. 3. Find the PlayedCutscene lines, and edit them to read as follows: PlayedCutscene0 "15" PlayedCutscene1 "15" PlayedCutscene2 "15" PlayedCutscene3 "15" 4. Save and exit the file, and try again.

Installation Issues

Change Client Language

As of June 8, 2012, Blizzard appear to have restricted client language switching. Errors 81, 82 or 84 displays: The client does not match the accounts native language. Please, use the game native client. There is no known fix as of yet, as Blizzard controls the language restrictions from their servers.

Language change menu.

Client language files can be adjusted from the options menu. Once the change is applied, a patch of approximately 3 GB is downloaded. Client language cannot be changed back until this download reaches the 'playable' state, and one re-enters the client to change the language option again.

Available languages are:

• English (United States)
• Spanish (Latin American)
• Korean
• Chinese (Traditional)
• German
• Spanish
• French
• Italian
• Polish

"Updating game files" Issue

Some players are reporting the game getting stuck at installation in the "Updating game files" part.

Method 1 - Disable anti-Virus Software[citation needed]
Turn off anti-virus software and/or firewall. Load the setup file again. Run the launcher as administrator.

Method 2 - Connect using a different network adapter[citation needed]

The Blizzard Agent may be attempting to connect over the wrong network adapter. The following steps may resolve your issue: Open the Control Panel. Select "View network status and tasks". Select "Change adapter settings". Right-click on each adapter and select "Disable". Leave the primary adapter (the one that provides the main Internet connection) enabled. Only one adapter should now remain enabled. Check that the system is still connected to the Internet. Go to %PROGRAMDATA% and delete the Battle.net folder (if it exists). Retry the installer/launcher.

Method 3 - Delete/Modify Agent Files[citation needed]
Go to %PROGRAMDATA%\Battle.net\Agent Delete or rename Agent.exe. Edit Agent.db with a text editor. Change p2penable : true to p2penable : false

Installation Stuck At 10%

If the user has any connections configured in "Dial-up and Virtual Private Network settings" and they are set to "Dial whenever a network connection is not present," the install will not proceed past 10%.

Installation not doing anything

If the installation has yet to do anything, ensure that the secondary logon has been enabled. Do so by going through - Control Panel/Administrative Tools/Services, right-click Secondary Logon and proceed to enable it by setting the start up type to automatic.^{[citation needed]}

Low frame rate (OS X)

Low Frame Rate[citation needed]
Using settings in the D3Prefs.txt mentioned below, one can achieve a reasonable frame rate on e.g. the MacBook Pro Mid 2010 with the Nvidia GeForce 330M. Open the D3Prefs.txt file and set the following to options to 1: DisableTrilinearFiltering HardwareClass

Can not use ⌘ + Tab (OS X)

Check that Caps Lock is not enabled, as that disables ⌘+Tab ↹, although ⌘+M still functions correctly.

Game freezes after entering the gameworld

Nvidia's Multi-Frame Sampled Anti-Aliasing (MFAA) can cause this issue. MFAA is enabled if the game is "optimized" using Nvidia GeForce Experience.

Disable MFAA

Disable MFAA in Nvidia Control Panel
Open Nvidia Control Panel. Click "Manage 3D Settings", then "Program Settings". Select Diablo III from the dropdown menu. Scroll through the options and set "Multi-Frame Sampled AA (MFAA)" to "Off". Click "Apply".
