I recently encountered an issue after migrating my engine plugin from the Unreal Marketplace to Fab. Before Fab officially launched, I uploaded an update for the plugin, which was approved without any problems.
However, after Fab’s release, I started experiencing an issue when trying to install the plugin on any Unreal Engine version. The installation fails and I get the following error message:
“Install Failed – Could not download installation information. Please try again later. Error Code: MD-0011-0”
I initially thought the issue might be related to my system, so I asked others to test it for me, but they encountered the same problem. It’s worth noting that other plugins associated with my account install without any issues. This seems to be specific to this plugin after the Fab migration.
Has anyone else experienced similar issues with their plugins after the Fab migration, or does anyone know what might be causing this problem? Any advice or guidance would be greatly appreciated.
Migrate your plugin from Unreal Engine Marketplace to Fab.
Upload a new version of the plugin and wait for approval before Fab launches.
After the Fab launch, attempt to download and install the plugin in any Unreal Engine version.
Observe the installation failing with the error code: MD-0011-0.
Ask others to test the plugin installation to confirm the issue.
Expected Result
The plugin should install successfully in any Unreal Engine version without errors.
Observed Result
The installation fails with an error: “Install Failed – Could not download installation information. Please try again later. Error Code: MD-0011-0.”
Other users who tested the installation also experienced the same issue.
same here. i looked at the log for the Epic Launcher and it seems to be failing to find a manifest file. which plugins don’t have (assets/projects in the vault cache do though)
Thanks for pointing that out! It seems like the issue might indeed be related to the missing manifest file for plugins.
Let’s hope the team is aware of the issue and can fix it as soon as possible. In the meantime, it might be helpful if we confirm whether it’s affecting all plugins or just specific ones, like those updated during the launch process. Let’s keep this thread updated if we find any fixes!
Same error when I try to install NVIDIA DLSS plugin.
Here is the related log in EpicGamesLauncher.

I am experiencing this MD-0011-0 error with some of my plugins as well. It appears to happen to any plugin that I’ve resubmitted on Fab. However any that were migrated, without resubmitting a new version, install just fine.
This is obviously a really big problem and needs to be fixed immediately! Otherwise we’re going to start getting a lot of angry customers when they make a purchase and can’t actually download the plugin they paid for, or worse, request a refund and decide to go with some other plugin instead.
It looks like the issue has been resolved!
I was able to install my plugin successfully without encountering any errors. However, I noticed that the NVIDIA DLSS plugin no longer appears in my library. I suspect it might have been temporarily removed to address this problem. If you’re still encountering issues, I recommend checking your plugins to ensure everything is showing up as expected.
That’s frustrating to hear! It looks like the issue might not be fully resolved yet for every plugins. I was able to install mine, but I’ve noticed that in some engine versions, it doesn’t show up in the list of installed plugins, so I can’t uninstall it. Hopefully, they’re actively working on a full fix. Let’s keep each other updated if there are any changes!
Thank you for letting us know this is on your radar, it means a lot. For now our best bet is to just include ZIPs with our items, which ensures there’s at least a fallback method for people to download via the website until this is resolved.
So while this is very frustrating, the fact that we can now compile for more than just the 3 most recent engine versions, and include some ZIP downloads, makes a huge difference. That along with the “verify order” page makes this website way better for plugins than the Marketplace was.
We also recently fixed our username, since it had /sellers/Tracer%20Interactive in the URL. But now after it updated (if you click on our profile) you can see that none of our items are showing on our profile anymore. I already sent a support email about the profile page though, since it seemed user-specific.
But the JsonLibrary and HttpLibrary plugins were the ones we updated after the Fab launch, and are now giving this “MD-0011-0” error code. However our WebUI plugin installs just fine, and it was only migrated, but not updated yet. However we’re about to submit an update for that too, and I would imagine it’s going to break the moment this update we submitted goes through. So thankfully we were aware of this before submitting the update, and made sure to include a ZIP download just in case.
If you can have someone look into any of this for us, it would be greatly appreciated. Thank you!
