Battle net launcher extremely slow


My launcher is extremely SLOW. It takes a 1-2 minutes to initialize/logging in and then another until it becomes responsive and being able to click any buttons. Anyone else having the same issue? Inetcpl.cpl checked. Reinstalling done. Win 10 x64. Any advice is appreciated.

Hey Siawase,

While you may have already tried reinstalling, make sure you’ve tried these steps specifically:

  1. Uninstall the Blizzard app

  2. Next open the temp locations and delete any Battlenet and Blizzard folders you see in each location. Press Windows Key + R and type:
    • %APPDATA%
    • %TEMP%

  3. Finally go ahead and reinstall the app from here. Make sure you run as Admin.

You may also want to try disabling the hardware acceleration option by clicking the Blizzard logo > Settings > General > Advanced Settings > Use browser hardware acceleration when available.

Have similar issue, but this did not help.

The app ran flawlessly, until one day, it just did not start. I restarted PC, I reinstalled the app, I did also erase everything as you stated, but nothing happens. I ran the app as an administrator, after cca 1 minute the app starts and I can log in. Or can I? After I hit the Log In button, for a second it seems like it is loading, then the app disappears and it never starts. Once it randomly started after tens of minutes.

Every other app runs perfectly correct in my PC. Steam, Epic, Discord, browser, other games, everything.

Thank you, in advance.

if you have cox cable the bandwith is being compressed by cox cable unless you get a certain router by them it happened to me too.

Howdy Dodolinous,

That sounds like there is another program causing a conflict. Typically this is security software that may be blocking the app from working correctly. If you have security software, try adding the Blizzard app as an exception.

this customer support guys are just making fun of us I am serious. C’mon havent you ever downloaded your own game ? it’s just toooooooo slow just accept that your blizzard installer is total mess. my internet speed is 200 mb/s and I just tested it. but when I download warzone blizzard speed is just 4 mb/s . honestly I dont think there is any worse servers than blizzard’s. keep it maybe make it worse. good job

We’ve been given a system that has no support yet, wonderful, as if their service prior was not already comical.
