Package failed win32 bit

Hi. when i want to packaging my game for win32 i get this error . but 64bit is fine . I’ve checked : Engine\Build\Receipts. folder and there are no such file ( UE4Game-Win32-Shipping.target.xml ).

ERROR: Exception in AutomationScripts.Automation: Missing receipt ‘UE4Game-Win32-Shipping.target.xml’. Check that this target has been built.

what i missing here, do i need to build engine source to win32 or … ?

I’ve tried several times( Building and cooking ) and it worked .
