Unable to change database from POSTGRESQL to MySQL

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 
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?
