I use MySQL Community Edition and I solved this problem today.

goto https://dev.mysql.com/downloads/mysql/

download the ZIP archive of your desired version

Open the ZIP archive and go to “bin” folder

extract MYSQLDUMP.EXE where you want

Close the Zip Archive and open MySQl Workbench

In MySql Workbench goto to Edit > Preferences > Administration

Select the file that you just extracted in “Path to mysqldumptool”

Press OK and it’s done!
