Deploying a MSVC build is a bit annoying because of this redistributable stuff. Didn't it require admin rights for installing? In corporations a user often does not have enough rights for installing software. Therefore for deploying I prefer a MinGW build of Qt, it depends on such a old runtime library that it is available on all Systems (I know such builds run from Windows XP to 7).
For instance my deploy folder looks like this: deployed/translations/v_es.qm deployed/translations/v_tr.qm deployed/translations/v_de.qm deployed/v.exe deployed/libgcc_s_dw2-1.dll deployed/libstdc++-6.dll deployed/Qt5Core.dll deployed/Qt5Network.dll deployed/Qt5Gui.dll deployed/Qt5Widgets.dll deployed/platforms/qminimal.dll deployed/platforms/qwindows.dll deployed/printsupport/windowsprintersupport.dll deployed/imageformats/qgif.dll deployed/imageformats/qjpeg.dll "libgcc_s_dw2-1" depends on your MinGW build, could also be "s_sjlj" or maybe "s_seh". To see at which places Qt is looking for the plugin start the app from command line with the environment variable QT_DEBUG_PLUGINS=1 set. (see http://doc.qt.io/qt-5/deployment-plugins.html ) Another advantage of the MinGW build is that it could be done completely on a Linux system.
