I was trying to create a dump file from my MySQL database, but when I try it always gives me this error
Operation failed with exitcode 2
Using Windows 7, a far easier solution for me was to find mysqldump.exe from; C:\Program Files\MySQL\MySQL Server 5.6\bin\mysqldump.exe
copy it and then replace the MySQL workbench mysqldump.exe which is located in the root of workbench C:\Program Files\MySQL\MySQL Workbench CE 5.2.47\mysqldump.exe
Restart MySQL workbench and all should work fine.
