uic3 output "QWidget: Cannot create a QWidget when no GUI is being used"

:?: :whistling: ?( QT4.8.7: Uic3.exe deliver the message "QWidget: Cannot create a QWidget when no GUI is being used" independent of
parameter and without parameter too.

I have a 30 day evaluation enterprise version. I need urgent a solution, to give a reason for using of QT5.

I tryed to debugg Uic3.exe, parhaps I have problem witch 30 Day Evaluation? (attached Images). I habe 28 Days yet.
It is me suspect why te debugger spring under #ifdef QT_EVAL in the qt_gui_eval_init member of QApplication and crashes ther with this error message.
For my uic3.exe is the console application (QApplication::Tty), this "#ifdef QT_EVAL qt_gui_eval_init" in QApplicationPrivate::construct is me suspect.
If I set the next statement under the define block, the application crashes with memory access violation.

I have installed
and evaluate QT3, QT4.8.7 for VS2008 and QT5 for VS2013, VS2008 and VS2013 parallel to check the transfer
of the QT3 Project to QT5/VS2013. The QTDIR and PATH point to QT4 directories.
After the installation of QT5 and VS2013 (with the integration) I have this problem.
Before this installation uic3 worked correctly. I could convert my UI forms to QT4 format.
Now I have trouble to reverse the situation.
I need uic3 working.

I checked
in dependency walker: uic3.exe depends of msvcp90.dll and msvcr90.dll. I placed
this too Dlls in the path. Perhaps there is some problem.
