I tried to reinstall Creative Cloud on my iMac Big Sur but it doesn’t work: error 81. I saw that I have to access the Activity Monitoring because there is another installation process for Creative Cloud, but I can’t find it. It seems that there is no active Adobe process on my Mac, but I can’t install the Creative Cloud package. Someone could help me? Thanks!

In addition to all other advice, the current Creative Cloud app doesn’t seem to support Big Sur (macOS 11) anymore:

@Emanuela_Navone1680 , thanks for posting. Error 81 occurs because another process or task is conflicting with the installer. Please see https://helpx.adobe.com/download-install/apps/troubleshoot/error-codes-1-99/error81.html for information on how to close the conflicting application or service.
