pre-compiled Qt SDK installation - always segmenation feults

[Lapsio]

Hello. I'm having some technical troubles - I've installed Qt SDK from Nokia webpage, but when I'm trying to compile anything in Qt-creator it gives internal compilator error - segmentation feult in QtCore. I've even tried to compile empty project by file->create new project, but it also gives this error. Is there better way to install working Qt SDK on Windows 7 x64? Or is it just error caused by my system?

On second computer I've got installed SDK 1.4.1 on x32 XP and it works correctly, so I wonder if installation new version on XP will help, or just destroy my last working SDK.

Compiling the project will not be giving you a segfault in QtCore, running it may. What compiler are you using? What version of Qt? Are you running the program from inside the Qt Creator IDE, or in a deployed setting?
