During our search for information on how to set and add environment variables during the LNR installation process, we discovered that only a limited set of environments can be changed, including II_INSTALLATION, II_CHARSET, II_DATE_FORMAT, II_DECIMAL, II_MONEY_FORMAT, and II_TERM_INGRES. However, it's worth noting that II_TIMEZONE_NAME can be set after the installation, and new environment variables can be added as well.\n\nTo simplify the installation process, we recommend using the silent installation method, which involves using ormsiexec.bat to install LNR. We suggest conducting a trial run first to ensure that the process runs smoothly. This method can potentially reduce installation effort.
