General

Unfortunately Epic has currently broken/disabled the ability to submit updates to Marketplace Products so this hotfix cannot be submitted at this time.

Using File Explorer, go to:
(replace UE_4.26 with whatever UE4 version you are using)

C:\Program Files\Epic Games\UE_4.26\Engine\Plugins\Marketplace\SteamCoreLite

Edit the SteamCoreLite.uplugin file with Notepad

Replace the content inside the .uplugin file with this:
