Quote - yes tried that everything was left as default when installing DAZ studio so following from the two answers above file path should be Cusersmy namemy documentsDAZ3Dstudiomy librarydataDAZ 3DGenesis

and that it is where I try to install it , to the my library where the Data folder is do you know what file it is looking for ? maybe I could try to find it manualy first

No, the path should be C:usersmy namemy documentsDAZ 3Dstudiomy library - the Data and so on foldrs are created/merged with by the isntaller, you just tell it where they are.
