When you start an Adobe application for the first time, the application begins the activation process and then displays thefollowing error message, "There is not enough disk space to start your application"
This is most likely a permissions issue.
Do one of the following solutions:
Solution 1: Set the Windows clock to current date and time, restart the computer, then activate your application
To access the system clock:
Solution 2: Add "Everyone" user to the Security settings of the DAT and FF1 file in the Product licenses folder.
In order to activate your application you must have read/write access to the DAT and FF1 files located in the Product Licenses folder on your hard drive. If you have less than Administrative level access to your system, then you might need to have an administrator grant you access to those files.
