Lotus 1-2-3, a legendary spreadsheet software, was first released in 1983 and gained immense popularity in the 1980s and 1990s. However, with the passage of time, the software became outdated and incompatible with modern operating systems, including Windows 10.

If you have the or other later 32-bit versions, you might succeed with Windows' built-in tools. Right-click the Lotus 1-2-3 executable ( 123.exe ). Select Properties > Compatibility tab.

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 While modern alternatives like Microsoft Excel have long superseded it, many organizations still possess historical financial models, macros, and data stored in native .WK1 , .WK3 , or .WK4 formats.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.
