I've logged a bug in the Adobe system here. This a huge issue for us. We have tens of thousands of users who now can't install Adobe AIR on the current version of Macos. Please help!

https://tracker.adobe.com/#/view/AIR-4198887

It affects any new installs of the Adobe AIR runtime on Macos 10.15 catalina.

Here's the full bug report:

Problem Description: Trying to install the Adobe AIR runtime from https://get.adobe.com/air/ on the current latest version of Macos 10.15 Catalina leads to an error "Adobe Air.framework is damaged and can't be opened".

Steps to Reproduce:

1. Make sure you don't have Adobe AIR installed on MacOS Catalina.
2. Try to install the runtime by downloading version 32 (latest) of the AIR runtime from https://get.adobe.com/air/

Actual Result:

The installer launches, but after it finishes installing you get an error message (after dismissing the final installation dialog):

"Adobe Air.framework is damaged and can't be opened"

As a result, any .air applications cannot be installed under MacOS.

This is a MacOS Gatekeeper Issue. I believe the Adobe AIR.framework needs to be correctly signed.

Expected Result:

The Adobe AIR frame framework should install correctly. But it does not.

Any Workarounds:

Opening up a terminal and running the following command removes the qurantine bit and allows the AIR runtime and installer to function correctly:

sudo xattr -r -d com.apple.quarantine /Library/Frameworks/Adobe\ AIR.framework

This is obviously not an acceptable solution.
