I've got information that Arbortext editor is supported by Window 10, 64-bit version.
But, when I look in the compatibility metrics, Window 10 is not listed. See attached image.
I'm not sure where you got that product matrix from, but the latest matrix clearly indicates Windows 10 support:

That's for Arbortext Editor 7.0 M080. From memory, I think they "officially" certified for Windows 10 in 7.0 M030?
