After a clean install of my computer I thought it was time to go from Qt4 to Qt5 but now I run into some problems.
I installed MSVC2012 express i.c.w. Qt 5.1.1 for Windows 32-bit (VS 2012, 511 MB) on my windows 7 machine.
When I build my programs in debug mode it all works fine, but when I build in release mode I get error -1073741511 (dll missing), I thought it was something in my project so i started a fresh gui project, but still the same error.
When I run the program from windows explorer (after adding the needed dll's) i get the error message: cannot find entry point ?script@QChar@@QBE?AW4Script@1@XZ in dll-file QtCore.dll. (translated from dutch)
I have no other Qt install so it is not a different version of the dll.

Does anyone know how to fix this?

Thanks in advance
