A Genshin Impact “game files download error” usually comes from one of four conditions: an unstable or restricted connection, incomplete or corrupted resource files, insufficient free storage, or security software blocking the launcher. Start with the least destructive fixes: change networks (or use wired Ethernet on PC), disable VPNs and proxies, confirm free space, restart the device and launcher, then run HoYoPlay’s Repair Now integrity check. Reinstall only if repair fails. A progress bar at 100% may still be verifying resources, so do not force-close the launcher immediately.
Why does Genshin Impact say “game files download error”?
The message is a symptom rather than a single diagnosis. HoYoverse describes Error 9908 as a problem downloading game files caused by network issues or corrupted data. The same pattern can appear when storage runs out, a firewall or antivirus product blocks a launcher file, or a VPN, proxy, network accelerator, or restrictive hosts-file entry prevents contact with update servers.

On a PC, the launcher can also appear to stop when it has finished transferring data and is checking every resource for integrity. A displayed 100% therefore does not always mean the process is complete.
Unstable or restricted network
Packet loss, a weak Wi-Fi signal, router problems, captive portals, or filtering on a school, work, hotel, or public network can interrupt a large download. VPNs, proxies, and network-acceleration utilities can route the launcher through endpoints that reject or reset its requests. A hosts-file rule that redirects HoYoverse update domains can have the same effect.

Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)
Incomplete or corrupted files
An interrupted update can leave a partial archive or a resource that fails its checksum. The launcher then retries the same item and reports a download or verification error even though the connection itself is working.
Storage and background interference
The destination drive needs enough free capacity for downloaded archives, temporary extraction, and the updated installation. Other applications can consume that space while the launcher runs. Firewall rules and antivirus quarantine can also remove or lock a file the launcher needs.
What should I try first?
Use this sequence before deleting folders or reinstalling. It moves from reversible tests to more disruptive recovery and works for most PC and mobile cases.
- Switch to a known-stable connection. Try another Wi-Fi network or a phone’s mobile-data hotspot. On a PC, connect directly to the router with Ethernet if possible. If the download succeeds on the alternate network, the original network is the likely cause.
- Turn off traffic-altering tools temporarily. Disable a VPN, proxy, or network-acceleration feature, then retry. If you use a custom hosts file, check for entries that block or redirect game update services.
- Check free space on the installation drive. Remove or move large files if the drive is close to full. On mobile, check the device’s storage screen rather than relying on the size of the game shown in the store.
- Close competing applications and restart. Exit the launcher, restart the device, and close download managers, overlays, and other programs that may be using the drive or network.
- Inspect security software. Look in the antivirus quarantine and firewall history for a blocked launcher or game file. Restore or allow it only when you recognize the file and downloaded the game from an official source; do not disable protection permanently.
- Run the launcher’s repair check. In HoYoPlay, use the game’s Repair Now (integrity-verification) control, let it finish, and then retry the update.
How do I use HoYoPlay Repair Now?
Repairing is safer than removing the installation because it checks existing resources and replaces files that are missing or damaged.

- Open HoYoPlay and select Genshin Impact.
- Open the game’s launcher options and choose Repair Now (the label may be presented as a repair or file-integrity verification command).
- Allow the scan and any replacement download to complete without closing the launcher.
- Restart HoYoPlay and select Update or Launch to test the repaired installation.
For Error 9908, HoYoverse’s guidance is to address the network first, run repair, and reinstall if the corrupted or missing resources cannot be restored. Repair cannot correct a blocked connection, so a repeated failure after a successful scan points back to the network, storage, or security checks.
How do I fix the error on Windows PC?
Windows offers the most diagnostic options, but it also has the most places for a download to be blocked.
PC checklist
- Restart Windows and HoYoPlay, then repeat the alternate-network test.
- Use wired Ethernet when available; it removes Wi-Fi interference as a variable.
- Disable VPN and proxy settings for the test. Check any network-acceleration application separately.
- Review the Windows hosts file for entries that redirect game or update domains. Remove only entries you deliberately added, or restore the file from a trusted system backup.
- Check Windows Security or your third-party antivirus quarantine and firewall events. Add an allow rule for the official launcher only when the file is authentic.
- Run Repair Now in HoYoPlay and retry.
If these steps do not work, reinstall from the official PC launcher source. A clean installation replaces damaged archives, but it also requires downloading the complete game again, so confirm the connection and free space first.
How do I fix it on Android or iPhone?
On mobile, the practical order is the same, but the store is the official reinstall path and storage is shared with every other app.

- Force-close the game or launcher, restart the phone or tablet, and try the download again.
- Temporarily disconnect a VPN or other filtering profile. On managed devices, an administrator’s network policy may prevent the download.
- If the error continues, uninstall the game and reinstall it from Google Play or the App Store. Use the same account you normally use to sign in.
Mobile operating systems do not expose the same launcher repair controls as Windows, so reinstalling through the official store is the standard recovery when a restart and connection change do not clear the failure.
What do Genshin Impact error codes 9908, 9001, 9041, and 6001 mean?
Codes narrow the troubleshooting path, but they do not replace the basic connection, storage, repair, and security checks.

| 9001 | PC download failure. | Use the HoYoverse launcher-repair executable and instructions for your distribution. Epic and the official launcher have separate procedures. |
| 9041 | Download interruption. | Disable VPN, proxy, and network acceleration; verify or repair files, restart the launcher, and retry. |
| 6001 | PC network-connection problem. | Disable VPN or proxy, restart the router or modem, and test a wired Ethernet connection. |
| “Timeout, resource download failed, please try again” | An unstable-connection symptom. | Move to another Wi-Fi network or mobile-data connection and retry after restarting the launcher. |
Why is the download stuck at 100%?
HoYoverse states that when a download reaches 100%, the launcher verifies the integrity of game resources. The progress display can therefore remain at 100% while files are unpacked, compared, or replaced. Leave the launcher open during this phase instead of killing the process as soon as the number stops moving.
If it remains unchanged for an extended period, restart once and run Repair Now. A repeat failure after repair should be treated as a resource or connection problem; document the code and contact support rather than repeatedly force-closing the launcher.

When should I reinstall Genshin Impact?
Reinstall after the network works on another connection, storage is adequate, security software is not deleting files, and Repair Now still cannot complete. Reinstalling earlier can waste time by downloading the same corrupted data again.
Before removing the game
- Record the exact error code and capture a screenshot or screen recording.
- Confirm you can sign in to the account you intend to use after installation.
- Ensure the destination drive or mobile device has ample free space for the download and temporary files.
- Use the official PC launcher, Google Play, or the App Store rather than an unofficial installer.
After reinstalling
Keep VPNs, proxies, and network accelerators off for the first download. If the fresh installation fails in the same way on multiple networks, preserve the logs and escalate instead of repeatedly deleting and reinstalling.
How much storage does the game need?
Current HoYoverse support guidance is to ensure sufficient available storage; it does not publish one universal figure that applies to every platform, language package, and update. Older documents should be treated as historical context, not a current requirement.
A 2020 PC installation guide listed approximately 260 MB or more for the launcher and 26 GB or more for the initial game files. A historical PC FAQ advised keeping more than 35 GB free during updating, while another historical summary cited 30 GB. Those numbers describe their respective documents and dates; later versions can require different working space.

Installing on an SSD can improve installation and file-processing performance compared with a mechanical hard drive. It cannot repair corrupted data or bypass a blocked network, and the SSD must be compatible with the PC and large enough for the game plus temporary update space.
What information should I send HoYoverse support?
Support can diagnose a failed transfer much faster when the report contains reproducible details rather than only “it will not download.” Include:

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- The exact error code or full timeout text.
- Device model, operating-system version, and whether you use the official PC launcher, Epic distribution, Android, or iOS.
- Your time zone or region and the approximate time of the failure.
- A screenshot or recording showing the launcher state.
- The networks tested (for example, home Wi-Fi, another Wi-Fi network, mobile data, or wired Ethernet).
- Every action already attempted, including repair, restart, security-software checks, and reinstall.
- The relevant log file. On Windows, the PC file is
Genshin ImpactGenshinImpact_DataPersistentDownloadError.log. Android installations have a correspondingDownloadError.login the game’s data directory.
Do not publish account passwords, authentication codes, or other private credentials in a support ticket. Attach only the diagnostic files and screenshots requested through the official support channel.
How can I prevent another download failure?
- Start large updates on a stable, uncapped connection and avoid switching networks mid-download.
- Keep VPN, proxy, and acceleration tools disabled until the update is complete, unless you specifically need one for a documented network requirement.
- Maintain free space on the game drive instead of waiting for the launcher to report low capacity.
- Check antivirus quarantine after major updates so a removed launcher file is not mistaken for a download defect.
- Let the launcher finish its post-download integrity verification before shutting down the device.
Frequently Asked Questions
Does Error 9001 have the same fix for the Epic Games version?
No. HoYoverse provides separate launcher-repair instructions for the Epic distribution and the official PC launcher. Use the procedure that matches where your copy was installed rather than applying files from the other launcher.
Are the old 26 GB or 35 GB storage figures still official requirements?
They come from older HoYoverse documents, including a 2020 installation guide and a historical update FAQ. Treat them as dated examples; current support says to provide sufficient free space because installation and update needs change over time.
Can an SSD solve a resource-download error?
An SSD can shorten installation and file-processing operations compared with a mechanical hard drive. It does not fix a blocked server connection, missing permissions, quarantined files, or corrupted downloads, so those causes still need separate troubleshooting.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What if the same error appears on two different networks?
After confirming adequate storage and checking quarantine or firewall events, run the launcher repair check again and preserve the exact code and DownloadError.log. A failure that follows the installation across networks is stronger evidence of damaged local data or a launcher-specific problem, which support can investigate.
