### Summary

Epic Games Launcher does not show any Unreal Engine versions.  
The “+” button under Engine Versions is disabled, and clicking “Install Engine” does nothing.

I can download Game Animation Sample 5.8, but when I try to open it, Launcher says that no Unreal Engine installation is detected.

I already tried:

- restarting the launcher
- running it as administrator
- logging out and back into my Epic account
- restarting the PC
- downloading and launching Game Animation Sample 5.8  
The issue still remains.

Launcher version: 20.3.7  
OS: Windows

Screenshots attached.

### Steps to Reproduce

Steps to Reproduce

Open Epic Games Launcher.

Go to Unreal Engine → Library.

The “Engine Versions” section is empty.

The “+” button is disabled.

Click “Install Engine”.

Nothing happens and no Unreal Engine version appears.

Game Animation Sample 5.8 can be downloaded, but when opening it, the launcher reports that no Unreal Engine installation is detected.

### Expected Result

The Epic Games Launcher should display available Unreal Engine versions and allow me to install Unreal Engine 5.8 by clicking “Install Engine” or the “+” button.

### Observed Result

The Engine Versions section remains empty. The “+” button is disabled and clicking “Install Engine” does nothing. Game Animation Sample 5.8 downloads successfully, but it cannot be opened because the launcher reports that no installed Unreal Engine versions were found.

### Additional Notes

The issue persists after restarting the Epic Games Launcher, running it as administrator, signing out and back into my Epic account, and restarting Windows.

Epic Games Launcher is installed on drive D:. Game Animation Sample 5.8 downloads successfully, but Unreal Engine itself does not appear in the Engine Versions section.
