error running Qt application

I installed the Open source Qt 4.3.4 on Windows. I was able to successfully compile the program. But when I double clicked on the exe in the release folder, I got a error pop up "Entry point for function _Z5qFreePV not found in QtCore4.dll. Can someone help me in solving the problem ?Thanks.

RE: error running Qt application

Are Qt dlls on %PATH% or next to your application?
Try to run executable from console.
If you have installed MS PSDK, then open executable with depends.exe (or download from http://www.dependencywalker.com/).
What have been used to install/compile Qt library? mingw32 or msvc.

Fighting fire with fire.

RE: error running Qt application

The Qt DLL' are on %PATH%...I also tried to run it from the console..the same error. OK, there was actually an error saying I dont have msvcp80 and msvcr80.dll's after which I downloaded them and copied them into the Qt's bin folder...after this I get the 2entry point not found" error...and I use the mingw tool chain

I have also just recently installed Qt 4.3.4 and I'm using Visual Studio with it.
And I'm having similar problems as the thread starter here.

Building debug mode and running it goes fine, when I build the release and try to run the .exe file I get the following error:

"Entry Point Not Found"
"The procedure entry point ?removePostedChildInsertedEvents@QCoreApplicationPrivate@@QAEXPAVQObject@@0@Z could not be located in the dynamic link library QtCore4.dll."

Is there anything I can do?

The problem was that I had still dll libraries from Qt 4.2 lying around in my developing folder. Removing them removed the problem.
