Pro Tools Won't Open - Helper Tool Prompt Window Trying To Install
I have Pro Tools Artist 2022.7 Subscription. It was working fine before when I first downloaded it, now it will not open. I keep getting "Pro Tools is trying To Install a new Helper Tool" prompt. I type in my password and hit "Install Helper". It says to relaunch Pro Tools, but it still won't open. I just get the "Helper Tool" prompt again and again. I've tried all of the on-line suggestions that I could find such deleting any avid files in Library/LaunchDaemen and PrivilegedHelperTools, but still won't open.
I have a Mac mini running Mac OS Sierra 10.12
Please HELP!!
Thanks!
Mac mini, macOS 10.12
