Yet, 64-bit doesn’t support running 16-bit Windows-based programs because handles have 32 significant bits on 64-bit Windows. With WOW64, you can run 16-bit programs on 32-bit Windows of the same principle. The app can obtain additional info about the processor relying on the GetNativeSystemInfo utility. However, this restriction doesn’t apply to DLLs loaded as data files or image resource files.Ī 32-bit program can detect whether it is running under WOW64 by calling the IsWow64Process function (use IsWow64Process2 if targeting Win10). Yet, 32-bit processes can’t load 64-bit DLLs for execution and 64-bit processes cannot load 32-bit DLLs for execution. Windows offers interoperability across the 32/64 boundary for scenarios like cut and paste and COM. In this way, Windows can identify a 32-bit app and provide the accurate. The 32-bit File system is stored as Program Files(x86). Console, GUI, as well as service apps are supported. It isolates 32-bit software from 64-bit programs, which includes preventing file and registry collisions. WOW64 is embedded in the operating system and there is no need to enable it explicitly. It also allows for 32-bit (x86) Windows apps to run seamlessly in 64-bit (圆4) Windows and for 32-bit (x86) and 32-bit (ARM) Windows apps to run seamlessly in 64-bit (ARM) Windows.Īlso read: What Is the Difference Between 32 Bit and 64 Bit (x86 vs 圆4)? All 64 bit systems are compatible with 32-bit programs relying on WOW64, which is the x86 emulator that enables 32-bit Windows-based programs to run seamlessly on 64-bit Windows. In general, you can surely run 32-bit software on a 64 bit PC. Can I Run 32-Bit Programs on a 64-Bit Computer? A 32-bit can run on a 64-bit Windows without accessing all the features and memory that a 64-bit can offer.
Yet, a 64-bit program is only developed to run on 64-bit Windows. Usually, a 32-bit program is designed for 32-bit Windows and also for 64-bit systems.

This article ideated by MiniTool official web page answers the question “do 32-bit programs work on 64-bit Windows system” and tells you how to run 32-bit programs on a 64-bit Windows operating system (OS).
