If like to ged rid off all the trail version and other no longer neede applications it’s not sufficient to just drag the program icon to the trash can. Most appications tend to place files in
~/Library/Application Support and elsewhere. To find these files and remove them too you can either use the well known AppZapper (shareware about 8,- EUR) or the free AppCleaner. The latter does the exact same job for free.
