Error compiling

Hello everyone,

I installed WinAVR and then replaced some of its files with avrdude-5.11-Patch7610, then I copied files from avrdude-5.11-Patch7610 into Arduino-022/hardware/tools/avr/bin folder also.
But When I try to compile program in Arduino IDE appears this error compiling message "avr-g++. CreateProcess: No such file or directory".
Please, know somebody what can be wrong with it?

The first thought that comes to mind is that you have corrupted the GCC toolset that came with the Arduino IDE.
