On Windows NT you have to click on the icon for the setting system
parameters. In the window that opens, you have to set the
environment variables ABACUS_DIR and ABACUS_LICENSE_DIR.
If the file .abacus is stored in the the directory
C: 
abacusapplication and if the license file is stored in
C: abacus, the two environment variables should be set in the
following way.
ABACUS_DIR=C:\abacusapplication ABACUS_LICENSE_DIR=C:\abacus
