Clang Analyzer is disabled

The description below worked for qtc4beta1:

I'm using manully configured VC compiler for a long time by specifying INCLUDE,LIB,PATH variables in Environment of the Kit. it works without error last few years.
After upgrading to QtC 4 , clang analyzer was a new feature (in comm edition) for me but it was disabled in main menu and no visible actions in Debug selector mode after select Analyze from dropdown.
But if I'm changing compiler in my Kit from manually configured to auto-configured (by provided MSVS scripts , system env variables and some data from registry) it 's going to enable

For qtc4rc1 clang analyzer disabled always.
the functionality doesn't work for win platform as well as for ubuntu
