Can't open exe with qcustomplot?

Question

Qt Creator

I made an application with a graph using the qcustomplot widget. Then I made an exe file, threw all the files from release there, everything was as it should, like But when I open the exe file, I get an error "The code cannot be continued because the system did not find Qt5Widgets.dll ..." If I throw a file into that folder " Qt5Widgets.dll", a new error occurs "The procedure entry point was not found in the DLL ..." Tell me, what can I do?
