What you show here is the ArchiCAD installation folder. Nothing to install here.
You need to add the Artlantis-exporter "ArtlantisR-Studio_Out.apx" in the folder:
"C:\Program Files\Graphisoft\ArchiCAD 10\Add-Ons\Import-Export"
and place the file "CAtl.dll" in the main ArchiCAD folder:
"C:\Program Files\Graphisoft\ArchiCAD 10"
