Cannot download any game through the battle.net app

I have uninstalled and redownloaded the app, given permissions through all security/virus programs, disabled said programs, and cycled the router, but I still cannot download anything.

There are no issues downloading games though other programs (steam, origin).

There could be a number of potential causes for this particular error. One of which is a corrupted WMI

If each sub-section of the MSINFO shows “Can’t Collect Information”, resetting the Windows Management Instrumentation (WMI) Repository should fix this error:

Press Windows+Q and type this into the search bar that pops up:
cmd
Right-click on Command Prompt and select Run as Administrator
Enter the following commands into the command prompt window one at a time. Press Enter after each command. Any time you get a confirmation prompt, confirm the prompt. One of the commands may also tell you the WMI service is already started. This is okay.

net stop winmgmt
winmgmt /resetrepository
net start winmgmt

Now, exit the command prompt and restart your computer, then retest running the Battle.net application.

Try doing a power cycle on your system. Turn off all devices including the modem. Wait 60 seconds, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.

You can try switching your DNS settings to use a free public DNS servers instead of your ISPs Servers:

We do not have individual steps for specific modems or routers so if you need assistance accessing or updating the devices, contact the device maker/provider.

Sometimes firewall or routing software/hardware will have some advanced settings to prioritize and manage types of network traffic. Normally that is not an issue but we have seen situations where it can interfere with the delivery of the data for our games/voice chat.

Let’s try turning off these features:

QoS
SIP ALG
RoG (ASUS Routers Only)
Security firewalls (Some ISP provided modems)

Not all devices will have these options and the steps for turning these functions off will be different depending on the make/model/software version of the devices and programs involved. If necessary look at the documentation for your security and routing products to find out how to turn these options off.

In some cases there is a corrupt or misconfigured setting within the router or modem. We cannot say what that might be offhand but the easiest way to resolve these conflicts would be to factory reset the router and/or modem.

You may need to look up your specific model for the steps on how to do this and in some rare cases you may need to have this done by the ISP. Feel free to reach out to them for assistance if necessary.

Let’s manually clear the Battlenet Desktop Application and all supporting data from the system. This will not remove existing game clients.

  1. Open file explorer/file manager (Right Click Windows Start)
  2. Navigate to the folder where the desktop application would normally be installed. Delete that folder if it exists (usually program files x86)
  3. Type the following into the address bar (not the search bar): %APPDATA% and press enter.
  4. Delete the Bnet and blizzard folders inside the appdata folder if they exist.
  5. Repeat steps 3 and 4 with %PROGRAMDATA% %LOCALAPPDATA% and %TEMP%
  6. Empty the recycle bin.
  7. Now reinstall the app to the C: Drive.

Try running your system in selective startup mode: https://battle.net/support/article/200483

Create a new administrator account: Blizzard Support - Creating a New Administrator Account

Once the account is created, shut down the computer, wait 60 seconds, restart, log into the new profile and try the app/client.

If that doesn’t solve the issue, I recommend submitting a ticket. (Click your name at the top right, choose support, then contact support. Follow the prompts and be sure to include the requested system data.

Thank you very much for taking the time to respond to this. I’ve tried everything suggested in the post. Still nothing is working. I guess I will open a ticket.

Hello, I have the same problem, I uninstalled the game and now I can’t install it again, it keeps updating in a loop and when it finishes it presents the error that it cannot install because it is still updating the game, I will open a ticket too.
