Platform

Unreal Engine 5.4.4

Operating System

MacOs Sonoma 14.5 M2 Max

Solution found. It might be all Mac users who can’t download any FAB Unreal Engine assets. Why? Because ALL of the UE assets download manifest on FAB only list platform of [“Windows”]. Epic Game launcher requests mac as platform that leads to a 404.

SOLUTION:
Create scripting overwrite using a tool like Proxyman. Here’s what I had to do to fix this, simply overwrite the initial manifest request platform to mac, now magically everything works.

my setup:

Tyler_X · October 27, 2024, 6:41pm

@BGTITAN-DENIS We are currently looking into this, and will let you know as soon as we have an update!

Tyler_X · October 27, 2024, 7:31pm

The team has identified an issue that is causing some Unreal Engine format products to be unable to be downloaded through Macs, and are looking to roll out a fix for this soon! Thank you for reporting this!

Tyler_X · October 28, 2024, 3:14am

We have deployed an update to correct this issue. Please let us know if you have any further problems downloading from Mac devices.

r0bray · November 2, 2024, 4:36pm

This is not fixed. I have downloaded over a dozen asset packs on my Windows laptop that are giving me “LogFab: Error: Invalid Manifest” errors on my Mac laptop.

Seto · November 12, 2024, 7:44am

It’s not fixed.
Official examples are not able to download. ML Deformer Samples, Valley of the Ancient, Electric Dream Env.

PRP1986 · November 12, 2024, 8:07pm

I’m having the same issue. Many of my assets momentarily show as downloading before disappearing from the download queue. The log shows ‘ERROR: Manifest download fail’.

I’m also on a Windows laptop so it is not a Mac only issue.

Manchey · November 15, 2024, 3:43am

I was having the same problem and this solution worked for me! At first it still was not working but after I enabled SSL Proxy to see the HTTPS Response, it started downloading for me. Thanks for the tip!

PRP1986 · December 16, 2024, 10:31pm

Still having issues with so many assets that do not download, and show the “logfab: error: invalid manifest” error in the logs…this has been an issue for a lot of people since the launch of Fab and it still has not been resolved.

PenguinSlaver · December 17, 2024, 4:11am

Also wanted to bump and say I’m running into this issue with a freshly purchased asset on Windows.

shadyderper · December 19, 2024, 12:43am

Jumping on the thread to report my issue.

Windows
POLYGON - Elven Realm asset pack ($199.99 dollar product btw)

After clicking “Create Project”, the asset is queued for download then immediately removed.

GoatCliffs · December 19, 2024, 7:08pm

Also unable to add to project on Windows 10. Below is part of what was in the log. Doesn’t work for adding to a 5.5, project despite the description saying otherwise.

I am on Linux and trying to use an asset I bought on the marketplace, however Fab is hitting me with the “invalid manifest” error, any solutions??

ilkercakir · January 13, 2025, 11:37pm

GoatCliffs · January 17, 2025, 6:59am

This issue is still occurring. Can’t download some assets from FAB.

skfabby · January 17, 2025, 12:21pm

Hi folks. Have you double-checked that the products you’re attempting to download are compatible with your operating systems? City Sample, for instance, is not currently compatible with Mac or Linux.

PRP1986 · January 17, 2025, 4:46pm

This issue is still happening to me for platform compatible assets (not all assets, but numerous assets). For me it’s happening on Windows, and has been like this since the launch of Fab, so it is not a platform specific issue.

PadreZippo · January 17, 2025, 7:03pm

@PRP1986 Can you share some example assets that aren’t downloading? Are you seeing the same error message? It might be better to file a support ticket to more easily share logs, etc. with us.
