I have the same problem.

I downloaded QT 4.4.3 and compiled it with visual studio 2008.
My application runs in debug mode, while in release gives the error "The procedure entry point ??0QApplication@@AE@AAHPAPADH@Z could not be located in the dynamic link library QtGui4.dll".

Googling around I saw people solving similar problem by updating the dlls, which seems not to be an option here as 4.4.3 is the last version.

Any idea?

Thanks,
