Qt - Error 2 at compile time

Question

I just downloaded Qt SDK 4.8.1 and, after installing it, I simply tried to compile a default C++ project, but I got this strange error.

16:50:24: Runn

Answer 1

I create a new project with the same name in other folder, copy internal files except .pro.user file.

This work form me, I don't know why, but removing .pro.user file from my original project error continues.
