For millions of gamers around the world, Blizzard’s Battle.net client is the gateway to popular titles like World of Warcraft, Call of Duty, Overwatch, and Diablo. But what happens when Battle.net refuses to update or install your favorite games? One of the most common and frustrating issues is getting stuck at 1 percent during a download or update. Fortunately, there are multiple ways to resolve this issue and get back to gaming fast.
In this guide, we’ll walk through tried-and-true methods to troubleshoot the problem, explain why it happens, and help you get your Battle.net client working smoothly again.
Why Does Battle.net Get Stuck at 1%?
Being stuck at 1% usually points to a problem with one or more of the following components:
- Corrupted download files or cache
- Conflicts with VPN or firewall software
- Slow or unstable internet connection
- Background processes interfering with the downloader
- Insufficient disk space or file permissions
Quick Fixes You Can Try Right Away
Before diving into more technical methods, try these quick and easy fixes:
- Restart the Battle.net client: Close it completely, not just minimize. Use Task Manager to ensure no background processes are running.
- Pause and resume the download: Sometimes, this simple trick can jiggle the connection back to normal.
- Restart your PC and router: A fresh reboot can often resolve temporary glitches.
Advanced Troubleshooting Methods
1. Run Battle.net as Administrator
File permission issues can prevent Battle.net from writing or accessing directories. Running the app with elevated permissions can solve this.
Right-click Battle.net shortcut > Choose "Run as administrator"
2. Clear the Cache
Corrupted cache files often lead to download stalls. Clearing them forces Battle.net to fetch fresh data.
- Exit the Battle.net app.
- Open File Explorer and go to: C:\ProgramData\Blizzard Entertainment\
- Delete the Battle.net and Blizzard Entertainment folders.
- Relaunch Battle.net.
3. Check Your Internet Connection
Ensure you’re using a stable, high-speed connection. Avoid using mobile hotspots or public Wi-Fi for large downloads.
- If possible, switch to a wired Ethernet connection.
- Run a speed test to verify download/upload capacity.
4. Disable Security Software Temporarily
Firewalls and antivirus programs can interfere with data transfers. Try disabling them momentarily while downloading:
- Turn off your antivirus and firewall settings.
- Launch Battle.net and resume download.
- Remember to re-enable your protection afterward.
Note: If the download completes successfully with security software off, consider allowing Battle.net through your firewall permanently.
5. Free Up Disk Space
If your hard drive is nearing capacity, Battle.net may struggle to store game files. Ensure you have at least 20GB of free space before starting large updates or installations.
Use the Blizzard Repair Tool
Sometimes game files become corrupted and can halt progress. Use the built-in repair tool to verify and fix these files:
- Open Battle.net
- Select the game that’s stuck
- Click the gear icon next to the “Play” button
- Choose Scan and Repair > Start Scan
Still Stuck? Try Reinstalling the App
If all else fails, a clean reinstall of the Battle.net application can resolve stubborn issues:
- Uninstall Battle.net via Control Panel
- Delete remaining files from C:\Program Files (x86)\Battle.net
- Download the latest installer from Blizzard’s official site
- Reinstall and log back into your account
