HOME ENVIRONMENT must be set!
This message will pop up when you are trying to open GAMBIT incorrectly usually from double-clicking on the wrong executable within Windows. GAMBIT has two executable files (gambit.exe). The one that is invoked when you open type GAMBIT at the Command Prompt is located in the Fluent.Incntbinntx86 directory. The other gambit.exe file is located in the Fluent.IncGAMBIT 2.xntx86 directory. Double-clicking on this executable will produce this error message.
