Reading through the Release Notes for R43: please note, that R43 is the last wysiwyg release which will be supported on Windows 7 and Windows 8.1. wysiwyg R44 will only be supported on Windows 10 Questions: Does this mean R44 can be installed on Windows 7 & 8.1 but you won't offer any support for problems on those systems? Or will R44 refuse to install on Windows 7 & 8.1? We run 7x Dongles across 12 or so machines, which are a range of Windows 7, 8.1 and 10. I'd like to know if we will be needing to purchase a bunch of Windows 10 licenses in time for R44. While we're here: Are you able to give us some insight into why you're moving on from Windows 7/8.1? Also, how is the data we're providing via CEIP helping with these decisions? e.g seeing more program crashes with older OS, or better performance with newer ones, etc.
