I have an Imac(Sierra) and have purchased Adobe Elements 2018 and downloaded it. However I can't install it because the message says because of security Amazon is not authorized to download to my computer. What should I do?
I have an Imac (Sierra) and have purchased from Amazon a copy of Adobe Elements 2018. I tried to install it and see a message from Amazon something about security and the Amazon site not being allowed to install software on my computer. How can I get the computer to allow this program to be installed?
