Download the OrcaLauncher installer (install_orcalauncher_x64.exe) or archive (OrcaLauncher.7z). Install or extract it to your local disc. Once you run OrcaLauncher.exe, you should specify the path to orca.exe on your computer (Settings > Set path to orca.exe). Do it only once at first OrcaLauncher run. Add your ORCA input files by clicking “Add files”. Loaded files appear on the left-hand side of the program (Input files queue preview). If you want to correct some input file or just take a look at it, you should left-click on the filename in the table. The content of the input file appears on the right-hand side of the program. If you change an input file, don’t forget to save the updates (“Save” button)!
OrcaLauncher is ready to take off! Press “Run orca” button. The main window is hidden and the status window appears in the corner of the screen. Queued tasks will be started one by one following the initial order. Outfiles appear in the same directory as input files located and with the same base names.
A task may become either “Completed” or “Aborted” depending on the result of ORCA calculations. You can open your outfile in the file explorer by right-click > “Show outfile in explorer”.
