My understanding is that 2 of my often used programs will continue to run on Sierra but not on High Sierra. Therefore, I'd like to move from El Cap. to Sierra instead of to High Sierra so to save $100 for now anyway. Is it still possible to find the Sierra installer software so I can make a flash drive installer for it or is it too late? Thank you.

Just now I clicked on a link that has taken me to the App Store and Sierra is there. Am downloading it now. Tried every which way the other day to find it and couldn't. Will report how the link and download perform.
