运行VS命令提示符快捷方式或者它指向的批处理文件，如:

Run the VS command prompt shortcut or the batch file it points to, such as:

"C:Program Files (x86)Microsoft Visual Studio 10.0VCvcvarsall.bat" x86

设置适当的环境，包括路径.

to set up an appropriate environment including the path.

顺便说一下，mspdb100.dll 位于 C:Program FilesMicrosoft Visual Studio 10.0Common7IDE 中.但无论如何运行快捷方式/批处理文件 - 它不仅仅设置正确的路径.

By the way, mspdb100.dll lives in C:Program FilesMicrosoft Visual Studio 10.0Common7IDE. But run the shortcut/batch file anyway - it does more than set up the correct path.
