# Launching OPTFEKO (Windows)

Use the most suitable option for launching OPTFEKO.

Launch OPTFEKO using one of the following options:
• On the Solve/Run tab, in the Run/Launch group, click the  OPTFEKO icon.
• From the command line in a terminal environment.
1. On the desktop, click the Windows Start button.
2. Type Feko + WinProp 2022.1.
3. Select the Feko + WinProp 2022.1 icon, from the list of filtered options.
4. On the Tools tab, select the Feko Terminal icon.
5. In the terminal (assuming the model with file name dipole.cfx is to be optimised) type the following command
optfeko dipole
and press Enter.
Note: The above steps launches OPTFEKO without any special settings. It is also possible to use parallel processing for optimisation.
