i've got problem with launching qt app on another pc (without installed mysql/qt).

P.S. On my pc it works fine.

Error "Driver[mysql] not loaded".

I try to deploy same project with sqlite and it launches on another pc normally, so problem is in mysql drivers/libs. I think i need add mysql .dll(s) (or something like that) Also i've got qsqlmysql.dll in sqldrivers project folder.

What can i do to launch my program on another pc. I'll be thankful for all your answers.

Database drivers are plugins. Either you forgot to provide them with your program, or you've put the plugins in a wrong folder. What you should do is use the qtwindeploy utility which is a part of Qt package. qtwindeploy will analyze the dependencies of your application and will automatically copy all the necessary Qt modules and plugins.

Here's a usage example from one of my projects:

windeployqt.exe --force --no-translations --release --no-compiler-runtime --no-angle binaries\32\FileCommander.exe

It will put all the necessary Qt modules into the same folder where the target exe is. Or you can specify another directory with the --dir <dir path> option. And don't forget the MSVC runtime.
