It works for me, didn't have an issue, if it didn't work its an issue with your pc, since this 3d lut creator is old it wont automatically find the version of Photoshop for you, you have change it in its settings and about loading files from Photoshop also its the same, you have to link to your Photoshop first, and 3dlc will trigger its Photoshop scripts there, its all documented on 3d lut creators YouTube channels and its website. You have to be disconnected from the internet otherwise it will check if its licence is legit or not and then it will revoke it. Best use a firewall.
