Fix Epic Games Error “IS-0003: Install Failed - Could Not Create Directory”
Source-checked · About 10 minutes
Answer
For Epic Games error IS-0003, clear the launcher's webcache, restart the computer, run Epic Games Launcher as administrator, then retry the game installation or update. This exact procedure applies to the stated directory-creation error, not every Epic install failure.
Check that the message is IS-0003: Install Failed - Could not create directory. Do not apply this page to another Epic error code because Epic publishes separate procedures for different failures.
2
Close the launcher
Exit Epic Games Launcher before clearing its cache, then make sure it is not still running from the system tray. Keep the game install path unchanged until the documented retry fails.
3
Clear webcache
Use Epic's current PC webcache-clearing instructions, then restart the launcher only after the cache process is complete. Clearing webcache affects launcher data, not ownership of games in your account.
4
Restart the PC
Restart the computer to release a stuck installer or folder handle. Sign back in to Windows with an account authorized to install software.
5
Run the launcher as administrator
Right-click Epic Games Launcher and select Run as administrator, then approve the Windows prompt only if it is the official launcher. This gives the launcher the access Epic directs for this specific error.
6
Retry the installation
Retry the update or installation and note whether IS-0003 returns. If it does, keep the exact error and contact Epic Support rather than deleting game folders or changing permissions beyond Epic's documented steps.
If the error code is different, stop and use Epic's matching support article rather than repeating the IS-0003 procedure.
If IS-0003 persists after the documented retry, provide Epic Support the exact code and install location; do not disable Windows security or delete unrelated directories.
