Additional Notes
Troubleshooting already attempted:
- Restarted the launcher and Windows.
- Ran the launcher as administrator.
- Deleted the launcher webcache.
- Repaired, uninstalled, and reinstalled the launcher.
- Tried a different Epic Games account.
- Switched between Games Library and Unreal Engine Library.
- Tried creating a project from the Game Animation Sample.
None of these steps resolved the issue.
System: Windows 11, NVIDIA GeForce RTX 4070 SUPER, 32 GB RAM.
I have never successfully installed Unreal Engine on this computer. I also encountered a missing MSI installer file error during a repair attempt through Windows Control Panel, but reinstalling the launcher did not fix the issue.
