If you bought from an authorized reseller, contact them with proof of purchase. | | Running on unsupported OS | Color Efex Pro 3.0 was designed for older OS versions. | Consider running within a virtual machine (e.g., Windows 10 in Parallels/VMware) or upgrade to the newer Nik Collection that is fully supported on modern OSes. |
