There is no urgent need to update your system. However, if you want to do so, go to the Compiler section and download the latest Windows installation package. IMPORTANT: Once you unpacked the installation package, first run the file uninstall_fortran.bat. This will remove the current Fortran release as well as any other additional software from your computer. Once your current Fortran package was removed, run the file install_fortran.bat and follow the standard installation instructions.
