Welcome to Petro-SIM Production 4.2

Please note that service pack 1 is now available to update Petro-SIM Production 4.2 to build 767! We strongly recommend that you upgrade. You can download the installer from the KBC SIM Suite Downloads page, where you should look for the KBC Petro-SIM Production v4.2 SP1 (build767) item. You will have to uninstall the existing version 4.2 install before you will be able to install the service pack.
