Diana, yes it is.

Make sure to get the right download for windows or for Mac.
I run Windows 8.1.
Downloaded the Zip (2-300 meg).
Opened the Zip.
Ran the Setup.
Setup downloads the full 2-300 meg again from a website.
Once done, it runs the program for the first time.
I choose the Buy/Settings button top right.
Entered the full Serial st://3406163355-3529620144
clicked validate license.
Registered without any issues.
Button changed to “Settings” from the former “Buy/Settings”
Clicking there I unchecked watermark.
This program is awesome, and does stuff that I rarely see in other apps.
