QSqlDatabase: QMYSQL driver not loaded with certain OS

My Qt App is already deployed and running/connecting just fine to the DB with my PC which is Windows 10 and other PC which is Windows 7(doesn't have QT installed), but somehow when I try to run the exe to a another PC which has Windows Server 2012 r2 standard or
Windows Server 2008 as OS it gives me an error for some reason. Here's my log:

Do you have any idea? Do I need to install something or missing plug-in to the server OS? Please help.Newbie here. Thanks.

Mysql libraries ? QMySql is only interface between Qt application and Mysql driver.

Did this issue ever get resolved. I am having the same issue where my application works perfectly on windows 7 or windows 10 but as soon as I try to install on a Windows Server 2012 R2 it gets a driver not loaded.
