Hi Susan,
Long time no see...
Install CC and login to your CW account. After it scans your products it will show you a list of everything you own (including the latest version of Sonar you purchased). If you have an external or second drive, it's best to put your downloads there since they will take up lots of space.
To change the download path: After installing CC and letting it scan your account,
but before running any installs of the applications, click the gear icon, then the path tab. Change the paths, then "save" to get back to the main window. Now you're ready to download to your designated drive.
If you just want to download the installers (but not install them), right-click and choose download.
