There was a time when many business systems, small utilities, internal tools, and custom applications were built during a very different era of computing. Back in the Windows 95, Windows 98, and Windows ME days, 16-bit applications were still common, even though the industry was already moving heavily toward 32-bit Windows programs. It was a transition period where older DOS-style and Windows 3.x-style applications still existed, while newer 32-bit software was slowly becoming the standard.
