Customization Wizard on Mac OS X

I've been trying to customize an install package for Acrobat Pro DC. I've been reading the official documentation and I don't know what I am doing wrong. These are the steps I've followed:

1) I created a file called com.adobe.Acrobat.Pro.plist and placed manually in <System Disk>/Library/Preferences/ and I added the information in the screenshot below.

2) Started the Customization Wizard and selected the plist file I created and also the Acrobat installer package.

3) I let the Customization Wizard create the custom package.

4) Installed Acrobat Pro using the custom created package.

5) Every time I launch Acrobat Pro, it still has all the cloud features and the updaters available.

I'm not sure what I am doing wrong. Any help will be appreciated.
