C: hard drive (boot drive) for dowloading and installing files

Hi, I do not want Adobe Creative Cloud to be installed on my C: hard drive.

I thought that setting up the install drive in Creative Cloud would fix the pb for the apps I want to install, but:

• the Creative Cloud software itself is installed on C:
• the apps are installed on C:
• and the download location off the apps that is used to download and dezip the files before the app is installed.

Does anyone can tell me how to solve this (HUGE) problem: my boot drive is a small SSD and I would rather not use it for temp files and non system software.

Thank you for your answers.
