Empty window on runtime

[athan_david]

My deployment machine has Windows XP Service Pack 3 on 32 bits, development machine has Windows 8 on 64 bits using Qt 5.1.1 with MinGW 4.8.
I did copy all required .dll, plugins, using Resource system for .qml files and images; everything seems to be in place. When I'm running Dependency Walker is telling me that is something wrong within Qt5Core.dll with MPR.DLL: http://postimg.org/image/m2f75gyrx/

How can I solve this problem?

P.S.: If any other information is required tell me.

Did anyone encounter this problem before?
Is WIndows XP too old to be supported?

Did you check out the windows deployment page for Qt 5.1 ?
The procedure is slightly different since you need additional to the dlls found by depends.exe some plugins. E.g. this one

The Qt Windows platform plugin platforms\qwindows.dll

Thanks for reply!

I did copy files:Qt5Gui.dll, Qt5Guid.dll, ..., a.s.o.; and the folder platforms which contains files: qminimal.dll, qminimald.dll, qoffscreen.dll, qoffscreend.dll, qwindows.dll, qwindowsd.dll. So this doesn't seem to be the case.

Is there anything which could cause this problem?
