I am currently working on ArchiCAD v.14 (yes I know behind the times). I have some interns to interview that are learning on v. 17 will their WIBU keys be able to open my ArchiCAD v.14 files if I allow them to install my v.14 software?</T></DIV> Thu, 16 Jul 2015 20:18:17 GMT https://community.graphisoft.com/t5/Installation-update/versions-of-ArchiCAD-and-individual-WIBU-keys/m-p/283457#M29323 Anonymous 2015-07-16T20:18:17Z https://community.graphisoft.com/t5/Installation-update/versions-of-ArchiCAD-and-individual-WIBU-keys/m-p/283458#M29324 Yes any later key can activate any "previous" AC version.

So a key setup for 17 can open 14 files Thu, 16 Jul 2015 21:13:33 GMT https://community.graphisoft.com/t5/Installation-update/versions-of-ArchiCAD-and-individual-WIBU-keys/m-p/283459#M29325 Anonymous 2015-07-16T21:13:33Z https://community.graphisoft.com/t5/Installation-update/versions-of-ArchiCAD-and-individual-WIBU-keys/m-p/283460#M29326 A key that runs AC17 will let you run all previous AC versions.
