Entry point not found after compiling with Qt 4.2

[mace]

Just downloaded qt-win-opensource-4.2.0-mingw.exe from a mirror and installed it.
Then I rerun qmake on one of my smaller project and compiled the project with no errors.
When staring the executable I get the error message attached.

Don't know what to do to get my application going. anything wrong wih the installation?

Did you remember to change your environment variables (especially PATH) to correspond the new installation of Qt?

Thanks for the reply.

PATH has got C:\Qt\4.2.0\bin and
QTDIR has got C:Qt\4.2.0 which corresponds to the installation location. So I think that should be ok.
I still had QT 4.1.4 installed when installing 4.2.0. Shouldn't have any effect or does it? I might try the same with uninstalling 4.1.4 and the reinstalling 4.2.0.

Reinstalling after uninstalling 4.1.4 didn't help.

Compiled Qt4.2.0 myself and now the Debug version works ok. But when compiling the release version I still get the error message when running the executable.

Found the solution to my problem by reading
http://www.qtcentre.org/forum/showth...e=hybrid&t=530

I had QtCore4.dll and QtGui4.dll in my Windows\System32 folder. Works fine after removing those dlls.

Thanks anyway.

Ok, good. The reason I told you to check the PATH environment variable was because I had a suspect it was using old versions of the Qt libraries.
