When ODBC is installed, a set of directories and symbolic links are set up to enable the existing ODBC user to operate with no operational impact, provided the installation uses the default installation directory.
When a non-default installation directory is used, the ODBC user must execute the script called enable_legacy_installdir to enable the existing odbc.ini and odbcinst.ini files to work with the new directory tree structure. The -b option specifies whether the existing ODBC InstallDir, the odbc.ini and odbcinst.ini are to be associated with a 32-bit or 64-bit ODBC Driver in the new directory tree structure.
