Clear Day Screen Saver

There seems to be an incompatibility problem / glitch / or software issue with this screen saver. I have an IMac 27 Desktop and also a MAC Pro 17” Laptop. Problem works great on my Desktop IMac 27 but does not work on my Laptop Mac Pro. On my Laptop it also shows on my AppStore icon that I have an update associated with Clear Day, but when I try to update it gives me an error message that the software could NOT update becasue it is not compatable with my MAC Pro 17 inch laptop ??????

Then I cannot seem to get rid of the update alert message from my App Store program.

What is the problem ??
