It will run on Windows 8.1 32 bit. &nbsp;It will NOT run on Windows 8.1 64 bit. &nbsp;On a 64 bit system you could install virtualization software (such as VMWare Player, VirtualBox) and then buy another copy of Windows 32 bit, install that in a virtual computer, and then run it in the virtual computer running on Windows 8.1 64 bit.<br />

It's worth noting, MOST (if not all) Windows 8.1 systems sold are 64 bit these days.

Hi<br />
<br />
16 Bit applications are mostly DOS compatible, and since Windows doesn't emulate DOS, it wont work on Windows x86 or Windows x64.<br />
<br />
To run DOS applications, you can use an emulator, like DOSBOX:<br />

You should try. 2003, you would not see many DOS apps around, so you can expect it to run.

I have a client that has an old app from 2003. I think that it is 16 bit, but I don't really know how to tell.<br />
Will this app run on Windows 8.1? DoI have to add anything special to enable 16 bit?

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.
