DLL missing problem

Following the instruction, I tested my first QT C++ application: TextFinder. It worked fine within IDE. However, after I close the IDE and run the .exe file, it failed and the error message said: minwm10.dll is missing. I guess I missed some important steps. Can some one give me some advice how to solve the problem?
Appreciate!

First you should be in release mode in Qt Creator.
Second , You should search your Qt path( mine : C:\Qt\4.7.0 ) to find mising *.dll . Then copy them beside your exe file
