问题
I have written a c++ application using Qt 5.5.1 compiled with msvc-12.0. Now I want to deploy the Application and I'm using the Qt Windows Deployment tool (windeployqt.exe). Using windeployqt produces a whole bunch of dlls that my application requires and it also creates a platforms directory where it copies qwindows.dll. From another stack-overflow post I saw that qminimal.dll might also be required and I have manually copied it as well in the platforms directory. In addition to the dlls pointed out by windeployqt, my application uses Boost Python libraries so I manually copied the dlls for boost-python/boost-system and the python27.dll libraries.
Now when I start the application on a different windows computer, the program simply doesn't start. Also it does not give any kind of error messages about missing dlls. I have installed the msvc-12.0 x64 redistributable packages. I used Dependency walker's profile option and I see that there are no missing dlls but the Application exits with code 1 (0x1) after it gets started.
Any ideas on where the problem might be. Thanks in advance.

The mostly likely reason was that Python 2.7 was not installed. Simply copying python27.dll file does not suffice.
