Installation Qmake issues

[Longin]

Hello
I still have problem with online installation. Problems are similar to bugs report here https://bugreports.qt-project.org/browse/QTIFW-394
especially: https://bugreports.qt-project.org/browse/QTBUG-33701
I have completed installation (Qt Creator, MinGW4.8, QT 5.0.2 for MinGW 4.8) getting error http://adolfik.ic.cz/bordel/1bug.jpg with clicking Ignore.
After installation I have problem (like guys in bugreport forum) with compilator settings (Tool->Build and Run etc) in QT creator. It warns "QT version is not properly installed, please run make install" and "qmake does not exist or is not executable".
I was trying to reinstall it with older version QT but it didnt help. Can someone help me? I really need this IDE for work

Problem is that i selected QT 5.2 (components for MinGW4.8) so i dont know why there is text about "5.1.1"
