Start with this quick answer
Identify where the 0% indicator appears first. On Windows, check the Epic Launcher queue, available drive space, network and current service status. On iPhone/iPad, confirm the installation method and regional availability using Epic’s latest iOS guide, then check the app store or device download. Do not use PC launcher file steps on a phone; the phrase “error code 0” may describe a different message.

4 quick checks before the illustrated walkthrough
Begin with these safe, focused checks, then follow the ten-image guide below.
Identify platform and exact message
Note whether the stuck progress is in Epic Launcher, App Store or another approved mobile store. Look at current Epic Games service status before changing files.
A 0% progress bar is not by itself a verified Fortnite error code. Outages can keep downloads from starting even on a healthy device.
PC: check install drive capacity
Confirm there is free space for game files plus temporary extraction and updates. Quit the launcher completely and start it again, then retry the download once. Pause competing downloads; test a stable connection without VPN or proxy changes.
Low storage can stall initialization or patch application. Repeatedly deleting download data can make the problem worse. A download-rate stall does not necessarily indicate a corrupt game.
iOS: check available install options
Use Epic's current country and store availability page for your iPhone or iPad. Check that the device meets the selected store's requirements and has free space. Try a normal app/store restart once; retry from the supported installation source.
Supported mobile installation channels differ by region and device. Do not follow outdated region-bypass guides or sideload shortcuts. Avoid deleting unrelated account data or changing Apple ID region casually.
PC: use launcher troubleshooting if persistent
Follow Epic Launcher support for stalled downloads and check file permissions. Include platform, store method, OS, drive space and displayed error text in the report.
Do not randomly remove Fortnite folders before checking existing files. Specific details separate a store failure from an Epic service failure.

Check Epic status for downloads
Look at current Epic Games service status before changing files.
Outages can keep downloads from starting even on a healthy device.
PC: check install drive capacity
Confirm there is free space for game files plus temporary extraction and updates.
Low storage can stall initialization or patch application.
PC: restart the Epic Launcher cleanly
Quit the launcher completely and start it again, then retry the download once.
Repeatedly deleting download data can make the problem worse.
PC: compare network stability
Pause competing downloads; test a stable connection without VPN or proxy changes.
A download-rate stall does not necessarily indicate a corrupt game.
iOS: check available install options
Use Epic's current country and store availability page for your iPhone or iPad.
Supported mobile installation channels differ by region and device.
iOS: confirm OS and available storage
Check that the device meets the selected store's requirements and has free space.
Do not follow outdated region-bypass guides or sideload shortcuts.
iOS: restart the store or device
Try a normal app/store restart once; retry from the supported installation source.

Do not randomly remove Fortnite folders before checking existing files.
Escalate with exact context
Include platform, store method, OS, drive space and displayed error text in the report.
Specific details separate a store failure from an Epic service failure.
Do not describe every stalled download as “Error Code 0.” Fortnite iOS availability is region- and platform-dependent, and unsupported distribution or account-region workarounds are not recommended.
What if it still happens?
Separate account, platform and service problems from local settings before using bigger fixes.
Only this one device has the issue
Compare the same account or mode elsewhere if safe, then focus on device-specific steps.
Other players have the same issue at the same time
Check Epic status and recent patch reports before altering local settings.
The issue began right after an update
A game regression is possible; record your patch timing and retest after official fixes.
One setting change helped only temporarily
Repeat the test with just that single change and capture a clear symptom report.
Need help with a repeatable issue?
Include platform, exact symptom, the steps you tested and any screenshot or short clip that helps explain it.
Official Fortnite Support ↗Quick FAQs
Is downloading at 0% the same as Error Code 0?
No. A 0% progress indicator is a symptom; any displayed error code must be recorded separately.
Can I use Epic Games Launcher troubleshooting on iPhone?
No. Mobile stores and PC launcher downloads have different steps.
Is Fortnite available through every iPhone store worldwide?
Availability depends on region and current distribution options; consult Epic's live installation guide.
Should I delete Fortnite files to free the download?
Not as a first step. Check space and launcher state before removing anything.
What if other games also cannot download?
That suggests a broader store, network or device issue.
