I was told when I updated to WIndows 10 that 11.4 will not workin Windows 10. I downloaded 15.1 and don't have any use for the new feartures or want to pay for them. I am happy to see that 11.4 will work.
The question is now, is the software backwards compatable? Meaning all the files that I have modified in 15, will they open and work in 11.4 or am I now stuck with Notebook 15?
