64Bits dll confilict with 32Bits project after using windeployqt for packing

I use Qt creator 5.10.0 in 64Bits windows 7.

I use VC 2010 32Bits complier.

I pack my .exe using windeployqt. But it introduced 64Bits dll like Qt5Gui.

And when I click the .exe error occurs: The application was unable to start correctly (0xc000007b)

It seems like my .exe is conflict with the 64Bits dll.
