@TOYSTORYLAB ,
I was reviewing the video and noticed that clicking the Install button triggers a refresh of the Fab Library assets in the background.

This indicates that the Launcher is refreshing at that exact moment, which interrupts the install action.

Try the following steps:

Clear the Launcher cache

  • Close the Epic Games Launcher.
  • Delete these folders:
    • …\AppData\Local\EpicGamesLauncher\Saved
    • …\AppData\Local\UnrealEngine\Common
  • Reopen the Launcher.

Unify installation paths

  • In Downloands Settings , set both the Default Install Directory and VaultCache to the same drive.

  • Example:

    • C:\Epic\Engines
    • C:\Epic\VaultCache

  • Try clicking Install again.

    If that doesn’t work

  • Check if the folder G:\EPIC\UE_5.6 exists. If it does, delete it.

  • Restart the Launcher and try installing again.

Verify permissions on external drives (G: and F:)

  • Right-click the folder: Properties - Security.
  • Make sure your user account has “Full Control”.
