Launch a map in 32bit mode

Hi .
I Want to test my map in 32bit Game launcher .

How can i do that ?

Developing via Unreal Engine Launcher

If you’re developing via the Unreal Engine Launcher, there’s a 32-bit game executable located at the following path:

UE4InstallationDir/4.0/Engine/Binaries/Win32/UE4Game-Win32-Shipping.exe

UE4InstallationDir is your installation directory, so you’ll need to replace it with a proper value.

Developing via source-code

If you’re developing from the source code available on GitHub, you will need to build the 32-bit game executable manually. You can do this by selecting the Win32 platform and a non-Editor configuration within Visual Studio. The editor does not compile under the Win32 platform, so you’ll need to use one of the following configuration names that is not followed by the word ‘Editor’:

  • Debug
  • DebugGame
  • Development
  • Shipping

After the build is complete, you’ll find a 32-bit executable in your Engine/Binaries/Win32 directory.

Running with the 32-bit executable

Same process that you would use for 64-bit executables. For example, to launch your map using the 32-bit executable that comes via the Launcher, you would create a shortcut with the following command line:

UE4Game-Win32-Shipping.exe C:\Path\To\Your\Game\Project\GameProject.uproject MapName

Replace the uproject path and map name with appropriate values.
