Devonsphere Express Installation Problem

I have downloaded Devonsphere Express to my Mac Book Pro and tried installing it.

It appears in the Applications menu but I cannot actually see it running anywhere.

I cannot uninstall to try again as my Mac says the program is actually active .

I am not sure what I am doing wrong and why I cannot access the application.

Advice appreciated please as to what I need to do to get it running so it is uasable.

You should see a leaf icon in the menubar at the top of your screen.

Yes, found it.

Thank you for your help.
