I have a new computer running Windows 10 and it only has Microsoft Edge (can't download Explorer 11 anymore).
I tried to install my Acrobat DC Pro (2015) and while it installed, it asked me to sign in. When I attempted to sign in I got the ""Update required. Your browser or operating system is no longer supported. You may need to install the latest updates to your operating system." I have the most up to date Windows 10 etc.
