The Lotus 1-2-3 Release 3.1+ install program checks to make sure it is running in true DOS. The OS/2 V2.0 virtual DOS machine DOS Settings allow you to create a DOS session that returns a simulated DOS value to the Lotus INSTALL.EXE and therefore fool it into thinking it has the real DOS.

Lotus 1-2-3 Release 3.1+ is usually started in DOS with the 123.EXE program. However, 123.EXE is a FAMILY API EXE file; it can be used to start both the DOS as well as the OS/2 version. Consequently, if we try to add a program icon to the desktop to start 123.EXE, OS/2 V2.0 will detect that it can be started as an OS/2 program and gray out the option to run it in a DOS session on the Session page of the Settings notebook. You also cannot use the Migrate Applications utility to add 123.EXE to the desktop, as it is detected as an OS/2 program.
This problem is overcome by starting 123.EXE from a DOS batch file. We then enter the DOS batch file name in the Path and file name field of the Program page of the Settings notebook.
Add the Lotus 1-2-3 Release 3.1+ icon to the desktop as follows:
The batch file should contain the following (Adjust 123MEMSIZE to accommodate the largest spreadsheet):
SET DOS16M = 2 SET 123MEMSIZE=2048
123.EXE
The Settings notebook should open.

The Lotus 1-2-3 Release 3.1+ icon should now be available for use.
