在早期版本的IDA中可以直接通过进程选项来设置Windbg的路径，但是在6.0之后这个菜单没了。
但是可以直接编辑ida.cfg文件来设置调试器路径，修改如下内容即可。
//-------------------------------------------------------------------------
// Processor specific parameters
//-------------------------------------------------------------------------
#ifdef __PC__ // INTEL 80x86 PROCESSORS
//
// Location of Microsoft Debugging Engine Library (dbgeng.dll)
// This value is used by both the windmp (dump file loader) and the windbg
// debugger module. Please also refer to dbg_windbg.cfg
// (note: make sure there is a semicolon at the end)
//DBGTOOLS = "C:\\Program Files\\Debugging Tools for Windows (x86)\\";将这一行注释修改为windbg的路径
DBGTOOLS = "C:\\WinDDK\\7600.16385.1\\Debuggers\\";
USE_FPP = YES // Floating Point Processor
// instructions are enabled
// IBM PC specific analyzer options
PC_ANALYZE_PUSH = YES // Convert immediate operand of "push" to offset
//
// In sequence
//
// push seg
// push num
//
