When you cannot write bitness-independent sequence files, use the Engine.Is64Bit property to specify that certain steps or portions of expressions execute only in 32-bit TestStand or in 64-bit TestStand.

Typically, you must dynamically load steps that execute conditionally based on bitness. If you preload steps that depend on bitness-specific code modules, the version of the step that does not match the bitness of TestStand fails to load and returns an error even though the bitness-conditional code prevents the step from executing.
