How to install GrailTool?

Hello! I am just starting to learn Grail, can you clarify if GrailConfigurator and GrailTool are the same thing? And how do I properly install GrailTool? Do I simply extract it anywhere and run GrailTool.exe?

Okay, the problem was with 1.2 version of the GrailTool, which is not working properly. The 1.1 version works just fine.
