However, briefly: In Windows, at the command prompt: set MATHEMATICA_BASE="C:\ProgramData\Mathematica" In a terminal under Linux (assuming ksh/bash): export MATHEMATICA_BASE=/usr/share/mathematica In Mac OS (again assuming bash): export MATHEMATICA_BASE=/Library/Mathematica Then start Mathematica from this same command prompt/shell instance using, e.g. Windows: "C:\Program Files\Wolfram\Mathematica\8.0\Mathematica.exe" Linux/Mac OS: Mathematica & Finally I would like to correct an error above. $UserBaseDirectory is associated with the MATHEMATICA_USERBASE environment variable. MATHEMATICA_BASE influences $BaseDirectory, not $UserBaseDirectory. The usage of either of these is essentially the same but the paths will be different.
