I did not copy any files.
I just set the file association of the “.uproject” file to “C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\UnrealVersionSelector.exe” by following these steps:
- right-click the .uproject file
- click “open with…”
- click “choose another app”
- click “more apps”
- click “look for another app”
- browse to “C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64”
- select “UnrealVersionSelector.exe”
- click “open”
