When using unreal engine 5.4 i installed it on my d: drive and it was working fine for a year. after updating the epic games launcher. epic games failed to realize that i had a ue5.4 installed in my d: drive and told me to install a new engine even tho i can still using 5.4 which was installed in my d drive now i when i am trying to install a plugin into the engine from my library i cannot since it has no idea i have a ue5.4 installed
Go to this folder:
C:\Users\{username}\AppData\Local\EpicGamesLauncher\Saved\Config\Windows
Open GameUserSettings.ini
Add a line under [Launcher] section:
CreatedProjectPaths=Parent path of one of your projects
Do not include the path of the project itself, only the parent path. It will pick up ALL the projects in that folder as well as all the engines (source or binary) that those projects use.
