Fix 2: Scan for missing or corrupted DLL files

Recently we see many gamers are having the same “DLL could not be found” issue. If that’s also your case, you can do a scan to find out what’s the problem.

You can follow this guide by Microsoft to scan manually. But if you don’t have the time or skills to do it yourself, you can give Fortect a try. It’s a professional Windows repair tool that can scan your system’s overall status, diagnose your system configuration, identify faulty system files, and repair them automatically. It gives you entirely fresh system components with just one click, so you don’t have to reinstall Windows and all your programs.

1. Download and install Fortect.
2. Open Fortect. It will run a free scan of your PC and give you a detailed report of your PC status.
   
3. Once finished, you’ll see a report showing all the issues. To fix all the issues automatically, click Start Repair (You’ll need to purchase the full version. It comes with a 60-day Money-Back Guarantee so you can refund anytime if Fortect doesn’t fix your problem).
   

If the scan doesn’t give you any help, take a look at the next solution.

Fix 3: Update all your drivers

The Battle.net not working issue could indicate a driver issue. In other words, you could be using incompatible, broken or outdated drivers. If you don’t remember when was the last time you updated computer drivers, definitely do it now.

You can update your graphics driver manually, by visiting the manufacturer’s website (NVIDIA/AMD), downloading the latest correct installer and installing step by step. But if you don’t have the time or patience to do that manually, you can use Driver Easy to update automatically:

1. Download and install Driver Easy.
2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
   
3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.(This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)
   

Once you’ve updated all your drivers, restart your PC and check if Battle.net works now.

If the latest drivers can’t fix the issue, take a look at the next method.

Fix 4: Install all Windows updates

Microsoft rolls out system updates to improve overall stability. Normally you don’t need to check for updates since it’s automatic, but it becomes necessary if you’re having computer issues. And this is especially true if you’re on Windows 11.

1. On your keyboard, press Win+I (the Windows logo key and the i key) to open the Windows Settings app. Click Update & Security.
   
2. Click Check for updates. Windows will then download and install the available patches. It might take some time (up to 30 mins).
   

Once completed, restart your PC for the changes to take effect. Then you can try to launch the Battle.net client.

If the issue is still there, you can move on to the next method.

Fix 5: Update Visual C++ Redistributables

The Visual C++ Redistributable install libraries that help you run most of the games and applications on Windows. If one of the libraries is missing or corrupted, you could run into trouble launching programs. You can use the following steps to install or update C++ Redistributables.

1. On your keyboard, press Win+R to invoke the Run box. Type appwiz.cpl and click OK.
   
2. Scroll down the list to locate Microsoft Visual C++ Redistributables. These are the libraries you may need to update.
   
3. Go to this Microsoft guide and download the Redistributable packages according to the ones you already have. You can use this guide to determine whether you’re on a 64-bit or 32-bit system.
