Is there an upgrade for ExamView Suite to Windows 8.1?
No, there is no upgrade for this application to Windows 8.1. I have checked the website and the system requirements provided specify that the software compatible either with Windows 7 or Windows 8. However, the difference between Windows 8 and Windows 8.1 is not that significant which means it's possible the software might work without errors on Windows 8.1.
