I usually Remove any program rather than do a over reinstall. What would you recommend me to do please.
OK, remove it if you wish. But you said "The last thing I want to do is a uninstall then reinstall". And just doing another install without removing it will work just fine.
I am using W7

Your settings files should be in:
C:\Users\
Your Personal Account Name\AppData\Roaming\Marine Aquarium 3
Are you perhaps now using a different account (User Name) on the computer? If so, that explains how you "lost" the settings and icon. The settings in MA3 are "per user" - of course.
