Help with "Creative Cloud Content Manager Damaged"- error window after OS upgrade

FYI one workaround I discovered for macOS is, in my case, is the problem can happen if your Privacy & Security settings only allow apps from app store and known developers, and then for one reason or another, macOS can no longer read/match the code signing certificate. I've had this happen not only with Creative Cloud Content Manager, but other apps as well. If you click the "?" you can see a helpful guide, but long story short:

1. Click "Show in Finder"

2. Select Open.

3. Same error will pop-up with new "Open" button. Click "Open" again. (WARNING: make sure you know the app belongs, and this is the likely cause, and contact a support professional if you're not sure. You could run malicious code if you don't take this warning seriously.)

Technically this is a security workaround, not a real fix, but it can buy you time until you can actually go through the trouble of clean wiping and reinstallling the affected app/s.

A qucker solution that works for me for Adobe SDL (Shared Device License for Enterprise users) on Mac is killing all Adobe CC apps and deleting the Content Manager. It will reinstall itself when you launch an app. 

reset the cc desktop app by making sure it's in the foreground, then press:

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R


if that fails, repair per https://helpx.adobe.com/download-install/kb/creative-cloud-install-stuck.html


if that fails and you have windows, open your control panel > add/remove programs > cc desktop app > repair

if that fails, uninstall using the correct uninstaller from https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-messaging and then reinstall using*


if that fails, do a clean cc install carefully following each applicable step:

uninstall every cc app including preferences per https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html

then uninstall the cc desktop app, again using the correct uninstaller per https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-messaging

clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html

check for, and if available, update your os

if windows is your os, repair all ms visual c++ versions that can be repaired (use google if you don't know how to do this)

if windows is your os update your ms visual c++, if it can be updated (use google if you don't know how to do this)

restart your computer (don't skip this)

reinstall the cc desktop app using the "alternative download links" at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html

use the desktop app to install your cc programs/trials

NOTE: win 11 users that have trouble with the latest win 10 installer often have success with the older win 10 installer.

Hi @xanthian212 ,

This seems like an issue related to the Creative Cloud Desktop Application. This is the Enterprise and Teams community. Would be moving this thread to the Creative Cloud Desktop Community for better assistance and resolution of your issue.
