Deployment of application on windows with sqlite failed

Hi ! I'm using Qt 4.7.1, on Windows 7.
I've built an application using qsql, and native qt sqlite implementation.
Building on my machine, works, running on my machine works.
Running on my laptop, where there is not installed the qt environment, but there are installed a lot of programs, using qt.
Running on my friend computer, doesn't work, it shows "Driver not loaded".
I searched on google, and it seems a plugin problem.
I've tried to create a folder named plugins, with a subfolder, named sqldrivers, and put a dll i've found in my laptop system, the qsqlite.dll i could not find it on the internet, by the way, called qsqlite4.dll.
But doesn't work either.
How i can resolve this issue ?

By the way, the program loads correctly on all the machine, it shows the user interface, but just then it shows "Driver not loaded", and doesn't work.

Thanks in advance.

Marco.

I think is a bug, i've filed it.
Look at: http://bugreports.qt.nokia.com/browse/QTBUG-19841

I've resolved with a workaround.

Thank you very much anyway.

It sounds like one of the dependencies is missing. I would use depends ( http://www.dependencywalker.com/ ) to figure out what DLL's the program requires. Then check to make sure they are all present and in the correct directories on the machine where it fails.

Yes is missing qsqlite4.dll, because the program search it in C:\QtSDK\Desktop\Qt\4.7.3\mingw\plugins\sqldrivers

It says it can't find gpsvc.dll and ieshims.dll, but on my dev computer, where it works. So i think they are not important.
Now renaming qsqlite4.dll to qsqlite.dll on my friend's computer, it works.
