Error overview
| Error | Root cause | Detailed guide |
|---|---|---|
| Stuck at 0% / very slow | ISP throttling, cached partial file, DNS block | Stuck at 0% |
| Browser blocked / “dangerous file” | SmartScreen, Chrome Safe Browsing, antivirus | Browser blocked |
| “File not supported” / corrupt | Interrupted download, wrong extension, fake link | File not supported |
| Hash mismatch / checksum failed | File altered or incomplete during transit | Hash check guide |
Step-by-step
Toggle Airplane mode or restart your router. Clear browser cache/download history so the file starts fresh.
Change DNS to 1.1.1.1 (Wi-Fi → Advanced). Use the mirror closest to you from the direct download page.
Compare SHA-256 with the hash guide. If it matches, proceed; otherwise delete and re-download.
Use the targeted guides below (Stuck at 0%, Browser blocked, File not supported). Only after these fail should you use a VPN or another device.

We recommend downloading in one go. If you must pause, use a download manager that supports checksum verification afterward.
Only disable briefly after verifying the hash. Re-enable immediately after the installer is saved.
