怎么没产生.NMS文件啊？

1.Build the application with debug information.

2.If SoftICE is not already loaded, load SoftICE.

3.Start Symbol Loader.

4.Click Open to open the module that you want to debug.

5.Click Package source with symbol table .

6.Click Translate to create a new .NMS symbol file.
第六步完成后Symbol Loader提示：
Translating D:\\Program Files\\Compuware\\SoftICE Driver Suite\\DriverWorks\\cc\\Debug\\cc.exe. . .
Error: Can\'t find Visual C++ MSPDBXX.DLL in path. Add the DevStudio\\sharedide\\bin directory to path.
这是怎么回事啊，请多指教。谢谢
