Between 2005 and 2015, Volvo distributed Prosis on physical DVDs for offline installation. These versions are now outdated (no new truck models beyond 2016-2018). Some forums distribute ISO rips of these DVDs for "free." While you can technically run these offline, they will not recognize modern ECUs (Engine Control Units) on a 2020 Volvo VNR. It is effectively abandonware—useful for classic trucks but useless for current diagnostics.
