Can't find MySQL binary

Didn’t find any executable MySQL binary at 'C:/myserver or in path, correct the path in the *.conf (“MySQLExecutable”).
Could not populate the Login database, see log for details.

Did you install the mysql server already as part of the steps on the database installation process? You need to go to mysql folder in the program folder

C:\Program Files\MySQL\MySQL Server 5.XXX

you go there and open bin folder and the mysql.exe is in there

Ok but I have accidentally deleted mysql, sys and performance from trinity user

The mysql.exe does not stay open. And I cannot find another mysql to start the DB
