I don't think so.  The box had backup floppies and I don't think this
was one of the "make a single copy for archive purposes" nonsense that
hit early MS-DOS titles.

There isn't one?

Well... I haven't been big on the Rainbow in the past but I see in this box:

Rainbow 100 MS-DOS Operating System Version 2.05
AUTOSORT-86 for Rainbow 100
Microsoft Multiplan-86 Spreadsheet for Rainbow 100
Rainbow CP/M-86/80 Operating System Version 2.0
Lattice C 2.15
Microsoft MBasic-86 BASIC Interpreter for Rainbow 100
