Blizzard Launcher

File:Mists Beta Launcher-1 0 0 920-Mac-circa build15913-31Jul2012.jpg
**Blizzard Launcher** (the application may actually be called the "World of Warcraft Launcher") is a utility application introduced with patch 1.8.3 to ostensibly provide news links and a minimal set of pre-launch configuration options for the actual game and the patch downloader. Behind the scenes it would also theoretically provide some measure of scanning and protection from trojan viruses and third party cheat programs.

The launcher may effectively be replaced by the Battle.net desktop app at some point.

## Battle.net desktop app

File:Icon-edit-22x22.png**Note:** This is a **generic** *section* **stub**. You can help expand it by clicking File:Sprite-monaco-pencil.png Edit to the right of the section title.

In mid-June 2013, a new Battle.net desktop app was announced with a request for beta testers with the goal to unify launching of most Blizzard online games (Diablo III, Starcraft 2, etc.). The app was made available as an open Beta in August 14, 2013.

## Features

* Act as a scanner and warn the user of malicious software.
* Provide news links about WoW and Blizzard.
* Control the options of the Blizzard Downloader in regards to pre-patching.
* Update the game. *New in Patch 2.1.*
* Options button to show options panel.
	+ Minimal pre-launch game preferences.
	+ Patch downloader preferences.
	+ Button link to Parental Controls web page.
* Public Test button link to PTR login web page.
* ? button to show web links panel.
	+ Community page web link.
	+ Forums page web link.
	+ Blizzard Store page web link.
	+ Technical Support page web link.
	+ Parental Controls page web link.
* First run "optimization". *New in Patch 4.3.2.*
* Repair Tool option under the Help menu. *New in **Lua error in package.lua at line 80: module 'Module:Inlinegfx/img\_link\_data.json' not found.** Patch 5.0.4.*
	+ When selected, it will show "Repairing game data..." status with a blue status bar at the bottom with a large "Skip" button to the right.

## Controversy

There was a bit of controversy regarding the Launcher as it was scanning the computer for malicious software, which some people believed to be an invasion of privacy.

### Possible security issue

The new Launcher may present a security issue. It does not obey the 'default' browser setting of Windows,[*citation needed*] and thus launches Internet Explorer when any link is clicked. Although this may be fixed in the future, in the past the 'Trial' Launcher has been observed to have some links obey the Default setting, and other links not obey the setting. Thus it could be said that although the Launcher is claimed to aide against some malware, some of its behavior reduces security benefits that might otherwise exist.

## In Mists of Pandaria

**Lua error in package.lua at line 80: module 'Module:Inlinegfx/img\_link\_data.json' not found.** This section concerns content exclusive to *Mists of Pandaria*.

File:Icon-time.svg This section concerns content that is out-of-date. Reason: New look for Win launcher released on 31-Jul-2012.
The Windows version of the launcher has menus at the top-left of the window. The Mac version has the menus at the top-left of the screen (standard location).

## In Cataclysm

**Lua error in package.lua at line 80: module 'Module:Inlinegfx/img\_link\_data.json' not found.** This section concerns content exclusive to *Cataclysm*.

 File:Launcher-streaming-status-4 3 2-15148.jpg

In the upcoming expansion *World of Warcraft: Cataclysm*, the launcher will be updated to "stream" installation and patch data. The new launcher is broken up into three stages of download progress:

* **SETUP (RED):** Core game, or 5% of content, is being prepared. You cannot enter the game at this time.
* **AVAILABLE (YELLOW):** Base game, or 70% of content, is not completely applied. You can play, but your game experience will not be ideal. You should ideally have 1 MB/sec or better when choosing to play.
* **PLAYABLE (GREEN):** Extended, or 25% of content, is almost complete. You may begin playing at this stage with few game issues. You should ideally have 1 MB/sec or better when choosing to play.

The Updater and Downloader have been integrated closely into the Launcher, resulting in less application switching when patching and installing.

Later text, for patch updates, for color coded streaming status (percentages and other specifics were removed):

* **SETUP** Core game content is being prepared. You cannot enter the game at this time.
* **AVAILABLE** Major game content is not completely applied. You can play, but your game experience will not be ideal.
* **PLAYABLE** Final game content is almost complete. You may experience a few game issues while playing at this stage.

### Optimization

 File:Launcher-4 2 1-2650-optimization.jpg
As of Patch 4.3.2 on the PTR, the launcher now has an "optimization" feature.

It will reorganize the game files currently installed on your hard drive to integrate all previous patch files, essentially "cleaning up" what’s on your computer and reducing the full installation size and will process these cleanups with no additional hard drive space required beyond what the patch is adding. Because of that you may see them appear more frequently with patches.

Here is the message (it may launch a web browser to show this message) it gives when it first runs:

The Launcher is optimizing your World of Warcraft install. This is a process we run from time to time to improve game performance and reduce the size of the install on your hard drive.

The entire process will take approximately 15 minutes under normal conditions. Please do not close the Launcher or run World of Warcraft during this time.

Thank you for your patience!

## Wrath of the Lich King design change

 File:WoW Launcher New.jpg
With patch 3.0.8, the launcher was redesigned with a new look. Also added to the "Options" menu was a bare-essentials "Game Preferences" panel, "Downloader Preferences" panel, and a "Parental Controls" link to the "WoW Account Management" website.
