Can't find compiler executable in your configured search path's for LLVM D compi

[ravipun]

The message "Can't find compiler executables in your configured search path's for LLVM D compiler." appears on the bottom right of my screen when i start C:B 12.11 on my windows 7 64 bit.
I am a newbie and i don't know much but i tried to solve this problem, so i went searching for the solution.I somehow figured out that we need to give the directories for the compiler executables in Settings>Compiler>LLVM D > toolchain executables. So which files are for which settings?
Help.

Do you have the compiler installed on your system?
