Architecture (Windows Only)¶

This section describes what operating system architectures your game will run on.

Architecture

All architectures¶

Your game has only a 32-bit executable and therefore can be launched on both 32- and 64-bit operating systems.
Your product will be available to all end-users, regardless of their system architecture, as 32-bit executables run on 64-bit machines.
Choosing this option doesn’t create additional packages.

Only 64-bit architecture¶

Your game has only a 64-bit executable and therefore can only be launched on 64-bit operating systems.
Your product will be available only to users using 64-bit operating systems.
Choosing this option doesn’t create additional packages.

Separate builds for 32-bit and 64-bit¶

Your game has separate executables for both 64-bit and 32-bit operating systems, and, thus, different executables will be used on different systems.
Choosing this option will split every existing package into two (one for each architecture).
Your product will be available to all end-users, regardless of their system architecture, as 32-bit and 64-bit executables will be provided in separate packages.
