Unable to change database from POSTGRESQL to MySQL

I have newly installed the free standard version of the ServiceDeskPlus on windows 7 professional. By default postgresql is the only option available as database. I wish to use mysql for database.

I have been referring to the link

https://www.manageengine.com/products/service-desk/help/adminguide/introduction/setting_up_database.html#Configuring MY SQL

to change my database from POSTGRESQL to MySQL (version 5.7). I am able to configure mySQL using changeDBServer.bat but I cannot connect to the mySQL server. After configuring to mySQL, I cannot find the folder [ServiceDesk Plus Home] \ mysql \ bin

as mentioned in the step to connect to the mySQL server. Can someone please help?
