Qt mingw 4.8 configure for QtCreator 4.7.4

[devwatch]

Hello Community, i am new to Qt and not very experienced in that Program.
Now i have a Problem:
I installed QtCreator 4.7.4 (the big 1.6 GB Package with mingw 4.7 included).
Now i tried to Install an configure the new mingw 4.8 but i don't really know how to configure QtCreator to use the 4.8 Version.
I have installed QtCreator under C:\QtSDK and at the installation of mingw 4.8 the setup asked twice for Path of mingw and for Install.
I have choosen C:\QtSDK\mingw for the first Install Step and second he install a Folder named C:\Qt\4.8.0.

What should i do now? I have no other selection to build a 4.8 Version for Debug an Release of my Program.

Thanks for Help!

Qt Creator isn't that big. You're most likely to have installe the Qt SDK, which includes Qt Creator and the Qt libs. In C:\QtSDK should be an SDKMaintenanceTool application. You can use this to update your Qt libs version to 4.8.
