Hi,
Epic Games Launcher correctly detects Unreal Engine 5.4, but it does not detect my existing projects on my D:, I moved my projects to D: from default which was documents on C: because my C: had started to get it’s storage full, which all prevents me from adding Fab / Marketplace assets directly to them.
Current setup:
-
Epic Games Launcher installed in:
D:\Epic Games\Launcher -
Unreal Engine 5.4 installed in:
D:\Epic Games\UE_5.4 -
Projects located in:
D:\UE_Projects\MyProject -
Vault Cache located on D: (not C:)
-
Windows system drive (C:) is nearly full, so I avoid using Documents
Issue:
-
In Epic Launcher → Unreal Engine → Library:
- My Projects shows “No user projects found”
-
Marketplace / Fab:
-
“Select the Project to Add the Asset to” shows No compatible user projects found
-
Installing Fab assets (e.g. Beech Rose) fails
-
Plugin installation fails with errors fab-fab001 / fab-fab0001
-
-
UE 5.4 itself launches and opens projects normally when I double-click the
.uproject
What I’ve tried:
-
Opening the project in UE 5.4 (from
.uproject) -
Running Epic Games Launcher as Administrator
-
Restarting Windows
-
Disabling my Windows Firewalls
-
Clearing Epic Launcher webcache
-
Uninstalling UE and Epic Games again on my D
-
Deleting Epic manifest cache to force rescan
-
Setting Default Install Directory to
D:\Epic Games
Question:
How can I make Epic Games Launcher properly register projects located on a custom drive (D:) so that Marketplace / Fab assets can be added to them and required plugins install correctly?
Thanks.
