Hi,
In your case the application is compiled in Qt 64bit which is suitable for windows 64bit Operating system.
Compile application source code with Qt 32bit which can be used in both windows 32bit and 64bit.

@mjzarrin As @yuvaram said you first need to install Qt 32bit for your compiler (VS2013). Then you should have a new Kit in QtCreator for that Qt version and compiler. If there is no such Kit add one manually and select Qt 32bit and VS2013 32bit compiler. Rebuild your application using this Kit. Then use this tool to deploy it: http://doc.qt.io/qt-5/windows-deployment.html
