I just got a new computer with Win10 Pro, and did all the Windows Updates. It's as up to date as five minutes ago. The only one of the programs I always use that I can't install is paint.net. The installer won't even open. It throws up a box that says I need Win 10 version 1607, which was obsolete years ago. Am I now cut off from using this program forever? If so, that's going to be a giant inconvenience. IS there a solution to this? Thanks.
