# Configure PoPy

## PoPy Config File

The local settings of your PoPy installation can be altered by editing the file `<PoPy installation folder>\popy_config.pyml`.

We recommend that you do not alter this file unless you know exactly what you are doing.

## Factory Reset Options

If you edit your ‘popy_config.pyml’ and PoPy no longer functions correctly, please restore to the following default settings:-

    # path to graphviz dot.exe for creating diagrams
    graphviz_dot_path: auto

    # path to sphinx confuration options - used when generating html or latex
    sphinx_conf_folder: ${POPY_PYTHON_PATH}/conf

## Uninstall PoPy

Note that if you are moving your product key to another machine, it is wise to Deactivate PoPy before uninstalling. If you are upgrading PoPy then it is best to keep the current product key.

### Run the uninstaller

You can click on the shortcut at:-

    Start Menu > PoPy > popy_uninstall

Or you could, instead, run the .exe at `<PoPy installation folder>\popy_uninstall.exe`.

The uninstaller will remove the PoPy desktop shortcut and Windows start menu items, but does not change the Windows Registry.
