Error after a few days of working correctly (0xc0000005)

Hello guys, here is issue that plague me and I’m hoping someone has a fix.

First a little background. This is a fresh install of Windows 10 Pro this past week.
Drivers, and windows updates are current. I also have Origin, Steam, and Epic games all running without incident. I have tried the suggested fixes but nothing seems to work.

It started as Windows security detecting Battle.net as a Trojan Virus, quarantined it and stopped it all from running. I thought maybe some definitions were out of date and then installed Mcafee, re-did it all and the same thing happened. So I tried AVG instead, again same stuff while running realtime protection. So this time I installed the protection first updating it then disabled Realtime protection.

It worked seemingly for about a day, I shut down the PC, wasn’t able to come back until a few days later, wanting to enjoy a game and poof I get an error (0xc0000005)when trying to play HOTS or SC2.

Origin, Steam, and Epic games all still running without incident. It’s just Battle.net stuff. I did try to contact support but the site won’t let me submit all of my info as a ticket. I can send Msinfo and dxdiag to anyone needing that.

Thank you in advance for any help you may have to give!

Hey there EnzoMatricks,

The symptom makes me think it’s something with bad files or possibly a Windows problem.

Can you try creating and switching to a new administrator account to see if that helps?

If not, then nuking the Battle.net application, including some folders not normally removed with a basic uninstall, may help get things working.

  1. Uninstall the application - https://battle.net/support/article/30304
  2. Press Windows key + R and type in %temp%
  3. Delete anything related to Blizzard or Battle.net
  4. Do the same for %programdata%, %localappdata%, %appdata%
  5. Reinstall the application! - Downloads – Blizzard Entertainment
