I am trying to upgrade Adobe Flash in order to run the Lumosity Program. There is a very friendly process to do it. I press "Download now" Step 1 of 3. Then I press the "next" button for Step 2 of 3. Then it says "Thank You" Step 3 of 3 but there isn't a button to press to complete the process. The screen only has an advertisement for "Creative Cloud Photography Plan." What do I do to complete the software upgrade process?
