unable to install creative cloud on macos catalina

You may want to try this installation when starting your computer in Safe Mode. Try restarting holding the Shift key down, until you see the Apple and startup bar. It'll take longer to start up, but it's doing some system cleanup. Then, you need to log in (ensure you're using an Admin login). You'll need to manually start that CC app, but then try the install. 

Try Offline installer for Mac OS X10.2 or later .
