I am trying to export my database from MySQL Workbench but I get this during the export progress:
Running: mysqldump.exe --defaults-file=\"c:\\users
Also ran into this problem. Decided as follows: In the Workbench menu, go to:
Edit - Preferences - Administration
In the field "Path to mysqldump Tool", prescribe the path to mysqldump.exe, in my case "C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqldump.exe", click OK.
After that, the error no longer appeared.
