Let’s try to fix this: Can you tell us how you installed V-Play, where you using our installer from http://v-play.net/download ? Did you install all the latest updates? Regarding the MinGW issues: Can you clean up all manually added kits and restart Qt Creator? Does the MinGW kit then show up? Also, are you enabling the shadow-build option when creating a new project? You can ignore the general messages, these are only warnings from Qt internals.
