Problem with building project via release

Hello there. I’m using Windows 7/x64, Qt 5.3.1. Was trying MinGW 4.8.2, VS2010 OpenGL and VS2013/x64. Project builds and runs properly from QtCreator but standalone release doesn’t work. There is 0xc000007b error when trying MinGW or VS2010 and “can’t find plugin “windows”“ with VS2013. I tried to put platforms/ into release folder but then app just crashes. It happens with any project including new one. Thanks.
