Why does the 1xBet PC client crash on start?

1xBet PC Client Troubleshooting

Q: How do I fix SmartScreen or antivirus blocks?

Verify the installer hash, click “Run anyway”, or whitelist 1xbet.exe inside Defender/antivirus. Using the official PC hub mirrors prevents false positives.

Q: Streams lag or don’t load. What helps?

Lower stream quality (Settings → Video → 480p), disable hardware acceleration, and use wired Ethernet to stabilize HLS streams inside the client.

Q: Can I switch to browser mode instead?

Yes. The PC download hub explains how to pin the browser/PWA client to the taskbar while you troubleshoot the desktop app.
