    Damn, so even it sounded the same, the fix was not. You seems to copy files to correct/same place.

    Well, then I think Leonardos suggestion is pretty good, try to use the deployment tool and see if
    copy some extra dlls.

    I moved all the files and used Release this time, instead of debug

    Running from C:\LottoNCA\LNCA\Release\release
    all needed .dlls are there (sqldrivers folder present as well)

    Error persists :c

      :(
      if you
      qDebug() << QSqlDatabase::drivers();

      it does list sqlite?

        ("QSQLITE", "QMYSQL", "QMYSQL3", "QODBC", "QODBC3", "QPSQL", "QPSQL7") is what I see, but I guess it's because I'm running from inside Qt

          @danks_ do you get same list from if you run it standalone ?
          I get only "QSQLITE" as expected.

            @mrjj Weirdly, I do get the same list from standalone...

            I wasn't sure about how to get the list from standalone, since standalone doesn't show qDebug, so I did the following:

             QStringList testStr;
             testStr << QSqlDatabase::drivers();
             QString str = testStr.join("");
             str = testStr.join(",");
             QMessageBox boxQry;
                        boxQry.setText(str);
                        boxQry.exec();
            

            Standalone folder only has sqlite.dll inside of sqldrivers folder, I'm really confused now.

              oh so it list all drivers even it should only see the lite one.
              That is not what I would expect.

              I also checked in release build and still only got QSQLITE.

              Also I wonder a bit about
              db.setDatabaseName (File Path); error as I use that call.

              db = QSqlDatabase::addDatabase ( "QSQLITE" );
                  db.setDatabaseName ( DBPath );        
                  if ( db.open() )  ...
              

              Also Im using qt 5.4 so I wonder if setDatabaseName was dropped.

                Maybe I should go to 5.4 and try my luck :)
                I guess I'll let you know, thanks a lot for your help!

                  Well, there is no reason it should not work in 5_5. but could be fun to test 5.4 just to see.
                  tomorrow I will try 5_5 in virtual machine. I was planning to upgrade :)

                  You are most welcome. Sadly we did not find a fix.

                    @mrjj It's all about learning, maybe someone will post a solution sometime :) if 5.4 gets it done, there's no real downside for me haha

                      Absolutely. Yeah if we are lucky someone will show us the light tomorrow :)
                      I have this feeling it is something very simple.

                          That is good to hear !
                          Could also been some kind of setup problem with 5_5 but yeah it does
                          seems like a bug.

                          I will try with 5_5 and see it it fails for me too.

                          update:
                          Tested win pure 5_5 install
                          It worked by copying the DLLs ! ?
                          Even worked with no sub sqldrivers folder ...!
                          (in the release folder)

                          But when moved out of the virtual machines
                          it did want the sqldrivers folder to work.

                          So the current version of 5.5 via the online installer does seems to work in regards to sql.?!
