Downloading problem on imac with Catalina 10.15.7

[TSELFES0D44]

I'm getting signed out all the time I try to do anything with Adobe. I  tried to install it again and again but now I can't even move forward with the installation as it's signing me out constantly. It's happening only with Adobe, I think...

it's not clear where or when you're seeing a problem.  are you saying you are unable to install the creative cloud desktop app from here install the cc desktop app from here https://creativecloud.adobe.com/apps/all/desktop?action=install&source=apps&productId=creative-cloud because of some kind of sign out problem?

or did that install without problem but you're having trouble using it to install cc programs because you're being repeatedly signed-out as described here https://helpx.adobe.com/manage-account/kb/troubleshoot-creative-cloud-sign-out-sign-in.html and here https://helpx.adobe.com/in/download-install/kb/adobe-sign-in-loop.html ?

or something else?

In detail: I sign in adob.cm, I open my account (view account), and get access my apps and services. I ask downloading the Creative Cloud and the Creative Cloud Installer is downloaded on my desktop. I open the Creative Cloud Installer and double-click in order to install the app. I prosed to my system account authentication and the problem starts. The running app sends me to my browser were an automatic sign in is happening, the browser sends me back to the app, the app sends me back to the browser and so on… after 5-6 trials the app displays: Server disconnection and I try again and again without any progress. I work without firewall an with antivirus app closed…

i understood you up to, and including, this sentence "I open the Creative Cloud Installer and double-click in order to install the app".

this, i do not understand "I prosed to my system account authentication and the problem starts."
