Hi, I'm getting the same error, even after I moved all of the Affinity Photo Trial entries in the Applications folder to the Trash and then emptied the Trash. My situation is somewhat different in that Affinity Photo was purchased thru the App Store by a family member (our family uses iCloud family sharing and I am the organizer of the family). That family member was able to successfully download / install Affinity Photo. When I try to install it on my computer, I get the message "Affinity Photo failed to download Use the Purchases page to try again."
