Maybe, uninstall Adobe Creative Cloud application and start over.

With Norton turned off Adobe Creative Cloud works fast and fine. FYI, uninstalling C.C. involves saving all presets and actions in Photoshop and all other C.C. applications, uninstalling all Adobe applications, reinstalling C.C., reinstalling all Adobe applications, reinstalling all presets and actions, rearranging all operating windows of all Adobe products. Even if that all of that wasn’t required - if anything needs to be uninstalled it’s Norton. Thank you for responding. Advice is appreciated.

Hello @Bill123456
Oh okay…sorry, I’m not familiar with ACC.
Wow, I had no idea…reinstall is such a pita.
Thanks for helping familiarize ACC.

Hmm…wonder how I can reproduce
“Norton 360 blocking Adobe application”
“will not open when Norton Auto-Protect and Norton Smart Firewall are turned on.”

Wonder if I need to install other CC applications to reproduce.
fwiw ~ as I recall Adobe Acrobat Reader has some security settings see here

fwiw ~ see here & here

Hello @Bill123456
What CC applications are installed??

@Bill123456

Maybe, open case via Norton support.
I wish I was familiar with ACC so, I could reproduce as you report my side.

Adobe Creative Cloud application will not open when Norton Auto-Protect and Norton Smart Firewall are turned on.

Is this new behavior? Or, behavior since you’ve installed Norton 360?
Meaning…did ACC ever run okay with Norton 360?

========================================

Is your AAC install default with/without AGS?
Did you opt out sharing?

==============================================

as test: I’ve install ACC again.
Sorry, I’ve no way to create your Adobe experience. I’ve no Adobe trial applications or Pro applications.
Creative Cloud Desktop installs n’ opens…my Norton 360 does not object…that’s as far as I can get.
