Unable to compile on Windows 7 64bit

[Hans Uhlig]

I just downloaded a copy of D-IDE and it downloaded a fresh copy 
of 2.060 and I tried to compile a brand new hello world. Anyone 
explain what I might have incorrectly setup?

main.d:
import std.stdio, std.cstream;
void main(string[] args){
	writeln("Hello World!");
	din.getc();
}

compile output:
