My Avro 5.1 is working on Windows 8, but not on Windows 10. Can I get help to use it on Windows 10?
The software doesn't work in Windows 10. This is actually specified in the version history page provided by the developers on the official website.
Here is what is said on the page: "Windows 8.1 Compatibility Added, now works with Modern UI (formerly Metro) and Windows store apps".
You will have to ask the developer to update the application for Windows 10, else it won't work.
