A benchmark conducted on an Intel Core i5-8250U running Windows 10 22H2 showed:
A more robust enterprise solution involves running a full virtual machine using VMware Workstation Player or VirtualBox. By installing a 32-bit version of Windows XP or Windows 98 as a guest OS, users can install Lotus SmartSuite 9.8 natively. This approach offers perfect compatibility, direct printing, and seamless file sharing via shared folders. The overhead is low on modern hardware, and snapshots allow state preservation. lotus 123 windows 10

Windows 10 is a 64-bit operating system that has dropped support for the 16-bit subsystems present in 32-bit versions of Windows XP and earlier. Lotus 1-2-3 releases 1.x through 3.x are 16-bit applications. Consequently, attempting to launch a 16-bit Lotus executable on 64-bit Windows 10 yields the error: “This app can’t run on your PC.” Even the last 32-bit version (Lotus SmartSuite Millenium Edition, release 9.8) suffers from graphical glitches, broken printing, and failure to register OLE components due to deprecated security models and missing 16-bit installer stubs. The overhead is low on modern hardware, and
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.
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.
