Installing System Debug Symbols

To debug a crash that occurs during a system call, you will often need system DBG or PDB files, which contain symbols for Windows DLLs, EXEs, and device drivers. You can obtain these symbols from several places:

Error: No Matching Symbolic Information

If you attempt to debug a system call without having the proper symbols installed, the Visual Studio debugger reports the follow message:

no matching symbolic information found

Even if you install the latest debug symbol files, the Visual Studio debugger may report the same error. This occurs if you have installed a Microsoft application that updates core system files, such as COMCTL32.DLL or OLE32.DLL, to versions that are newer than the operating system version or service pack for which you have installed symbols.
