This information applies to all versions.
There is no separate installation required. DxO FilmPack is already integrated into DxO PhotoLab and only needs to be activated with a valid license key.
Open DxO PhotoLab.
On Windows: go to the Help menu → Enter your license key.
On macOS: open the DxO PhotoLab menu → Enter your license key.
Once activated, a dedicated DxO FilmPack Palette will appear in DxO PhotoLab. Some features of DxO FilmPack (for example, Contrast) are located in their corresponding feature groups. If you cannot locate a feature you know from the standalone version, use the search bar in DxO PhotoLab to quickly find it.
Please note that DxO FilmPack 8 requires DxO PhotoLab 9.
