Hi @pascal_5230,
Thank you for reaching out. Based on your description, I recommend the following steps to address the issue:
Update OS: Ensure all pending OS updates are installed and verify if the issue started after a recent update.
Reinstall CCDA and Create a New SDL Package: To rule out corrupted configurations, please uninstall and reinstall the Creative Cloud Desktop App on the affected machine. Additionally, create and deploy a new SDL package from the Adobe Admin Console to test for any issues with the current deployment. After completing the installation, please confirm whether you are still encountering UAC prompts.
Please verify the environment configuration, as firewall or group policy restrictions may be preventing the Creative Cloud Desktop App (CCDA) from updating itself.
If these suggestions do not resolve the issue please let us know we will proceed with additional troubleshooting steps.
