I would like to inform you that if you purchase Acrobat subscription individually, you get Adobe FormsCentral basic subscription. However, we do not provide FormsCentral with Creative cloud subscription. Please refer to the following link:- Subscription Options | Adobe Acrobat Pro.
If you do not have forms central installed on your machine, you may modify the installation to install the service:-
Control Panel- Programs and Features- Select Adobe Acrobat- Change
Modify Installation- Next
Custom Setup- Select Adobe FormsCentral- This feature will be installed on local hard drive- Next
Click update to start the installation
