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!

I’m doubling that.

I have the exact same problem. I tried literally everything.

Cmd commands,
Deleted-regenerated launcher installation folders
Reinstalled the launcher
Reset-ed the router
deleted redundant registry keys
Reset the network settings of my PC
The list goes on and on.

The problem persists and I can’t download any Unreal version from the launcher right now.

Hello Leon!

Same here - I can download UE5.6 and 5.7, but not 4.27 or anything below it. My friend had the same error and couldn’t download UE4 or UE5 either. But today, he tried downloading UE5.6 again and it worked.

I’m not the only one: a friend of mine from another country is also getting the same error when trying to download UE4.27 or older versions. I’ve spent hours trying, and it’s been three days now with no luck downloading UE4.

What’s funny is that some Fortnite players are getting the same “MD-DL-0” error. I did some research and found that the issue might be related to Epic Games’ manifest servers. I’m not completely sure… but it does seem like a global issue happening at random.
