Being a registered user, you can use GOM Correlate to create new projects, import point clouds or basic CAD formats.
For this, please check the box "Install for all users" during the installation process. If you are not registered yet, you can easily create your GOM ID afterwards.
If you only want to open existing projects and edit them – without creating new projects or importing data – you can use GOM Correlate Lite. In this case, uncheck "Install for all users".
