UnrealLightmass.exe unable to start (0xc000007b) - w/ Dependency Walker info

  1. Have you run UnrealLightmass from the debugger or the whole UE4 and UnrealLightmass from within? Cause you need to run UnrealLightmass only in order to attach the debugger and give additional info.

  2. Did the debugger stop somewhere in the code or did you see normal message box with the error?

  3. Have you build the debug version of UnrealLightmass? To do this you need to change it’s configuration in Configuration Manager from Development_Program to Debug_Program.
