I am using the latest version of Visilogic. When I am trying to download a new project into this PLC, it says I need to upgrade the OS (currently v4.4) I first hit the Check button from the Install Operating System tab, then a window pops up. It then says that it will begin to install version 4.008, which is an earlier version then the one currently installed. Is this correct? I am getting no options to choose different OS versions from the dropdown menu. I attached a picture. I am new to Visilogic, so I am sure it is something easy that I am missing.
