Baler program configuration information is stored in the baler.ini file that is found, in a default installation, in the C:\Campbellsci\Baler\sys\inifiles folder. If this file is renamed or moved, Baler starts up as if it was freshly installed.
The same thing can be accomplished by starting up the program with a new working directory using the /WorkDir command line parameter. For more details, review the “Command Line Options” section of the Baler Instruction Manual.
