FormFix and FormDirector run on supported 32-bit or 64-bit Microsoft Windows operating systems:
FormDirector does not support use in a 64-bit Windows operating system for Itanium.
FormFix and FormDirector are thread-safe and can be used in multi-threaded applications.
Accusoft considers thread-safe to be when an application using this component can use multiple controls running in the same process, where they don't interfere with each other. The thread creating the control owns the control and is the only thread that can interact with it.
FormFix and FormDirector target the AnyCPU platform which allows an assembly to be executed in the same Common Language Runtime (CLR) as the process into which it is being loaded. The assembly can be executed on the 32-bit CLR or 64-bit CLR, however, the FormDirector assembly does not support execution on the 64-bit CLR running on a machine with an Itanium processor.
