Hello,

I am experiencing an issue when trying to install Unreal Engine 5.7 through the Epic Games Launcher.
Every time I attempt to start the installation, I receive the following message:

Installation Error
Failed to retrieve installation information. Please try again later.
Error Code: MD-DL-0

Here is what I have already tried:

1. Restarted my PC and router.

2. Checked my internet connection (stable, no VPN or proxy).

3. Launched Epic Games Launcher as Administrator.

4. Performed a full reinstall of the Launcher.

5. Deleted the following folders:

%userprofile%\AppData\Local\UnrealEngine

%userprofile%\AppData\Local\EpicGamesLauncher

6. Removed registry keys related to previous Unreal Engine installations.

7. Tried installing to a different drive and verified that there is enough free space.

Unfortunately, the issue persists and I am unable to install Unreal Engine 5.7.

I would appreciate your assistance in diagnosing this problem.
If you need any log files, please let me know which ones to provide and where to find them, and I will attach them in my reply.

Thank you!
