For users who only need to read legacy Lotus files rather than run the software, converters such as libreoffice --convert-to xlsx (LibreOffice), Gnumeric, or dedicated tools (e.g., CoolUtils’ Lotus to Excel converter) offer a practical alternative. These bypass execution entirely but may lose complex macros or formatting.
Simply enabling “Windows 95 compatibility mode” on a 64-bit Windows 10 system does not resolve the fundamental 16-bit execution barrier. Compatibility mode only modifies how the Windows API handles paths, DPI scaling, and user privileges; it does not emulate a 16-bit processor or the VxD kernel layer. lotus 123 windows 10
Running Lotus 1-2-3 on Windows 10 is not natively possible for 16-bit versions, but two effective pathways exist: DOSBox-X for DOS-based editions and virtualized Windows XP for 32-bit SmartSuite editions. For most users, converting files to a modern format using LibreOffice is simpler, but true operational fidelity requires emulation or virtualization. As Windows continues to evolve, legacy software execution will increasingly depend on community-supported emulators rather than OS-provided backwards compatibility.

A benchmark conducted on an Intel Core i5-8250U running Windows 10 22H2 showed: Compatibility mode only modifies how the Windows API
Abstract Lotus 1-2-3, released in 1983, was the first killer application for the IBM PC and dominated the spreadsheet market throughout the 1980s and early 1990s. With the discontinuation of its support and the evolution of operating systems, executing this legacy software on Windows 10 presents significant technical challenges. This paper examines the compatibility issues, available emulation and virtualization solutions, and the broader implications for digital preservation and enterprise data access.
Lotus 1-2-3 combined spreadsheet, graphing, and database functions in a way that revolutionized business computing. While modern alternatives like Microsoft Excel have long superseded it, many organizations still possess historical financial models, macros, and data stored in native .WK1 , .WK3 , or .WK4 formats. Furthermore, some users prefer Lotus’s keyboard-driven interface. Consequently, the ability to run Lotus 1-2-3 on Windows 10 remains a relevant, albeit niche, concern.
