Error when launching to windows

Hi guys,

I have this error message when I’m launching for a windows device:

LogPlayLevel: Error: ERROR: Stage Failed. Missing receipt 'D:\Hugues\UE Projects\my_proto\Binaries\Win64\'. Check that this target has been built.
LogPlayLevel:        (see C:\Users\lalib\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_4.21\Log.txt for full exception trace)
LogPlayLevel: AutomationTool exiting with ExitCode=103 (Error_MissingExecutable)
LogPlayLevel: Completed Launch On Stage: Build Task, Time: 2.017833
LogPlayLevel: Completed Launch On Stage: Deploy Task, Time: 0.000092
PackagingResults: Error: Launch failed! Missing UE4Game binary.
You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UE4Game <Platform> <Configuration

Also, I don’t have this path: D:\Hugues\UE Projects\my_proto\Binaries\

I have Built just before without any error messages.

Any idea

The error means that you dont have the binaries as you have already confirmed. It might be that the launching option is failing to compile the shipping binary to actually execute the.
Try going into visual studio and compiling your game code with shipping configuration.

Not sure what happened, but i solved my problem by creating a new project, then migrating my assets to it, now i’m able to launch for windows.
