My camera-lens combination is listed on the website, but DxO PhotoLab 4 won't install the module.

Within DxO PhotoLab 4 select Check For Updates  - found under the Help menu on Windows and the DxO PhotoLab 4 menu on Mac - and install the latest update if there is one available.

If your copy of DxO PhotoLab 4 is up-to-date, then most likely you own an older release which does not support your camera or your lens. We suggest that you download a trial version of DxO PhotoLab 4 to check whether your body-lens pair is supported.

You can purchase an upgrade to the latest major version from your customer account at a discounted price. Please note that upgrade pricing is only available if you own a paid license of DxO OpticsPro or DxO PhotoLab.
