Step 3 in the set-up indicates that you are purchasing. You get a 30 day trial with the option to cancel. I do not want a 30 day free option that I need to cancel. the website does not give you a choice. I have a Mac OS High Sierra 10.13.4. I googled Adobe Flash Player. I use Safari on my Mac. I just clicked on flash player on the website to instal. Is there a number that I can easily call and talk to you?
Ignore step 3. It's optional and the update has already happened. Very poor marketing of an optional extra.
