Qt 5.0.0 built with VS2012 : app exe doesn't run when outside Qt Creator

I have Qt 5.0.0 that I built with VS2012 successfully. My applications (projects) executes normally when compiled+run inside Qt Creator (2.6.0) but when I execute the exe files outside, it doesn’t. Compilation doesn’t throw any errors plus running the apps outside Qt Creator doesn’t pop-up any dialog boxes about any error. … or simply “NOTHING HAPPENS” I added all the DLLs it need together with the exe and it isnt working. I used dependency walker to check but everything is satisfied. Any help? thanks!
