I'm using Windows 7 Service Pack 1 x64, downloaded the symbols and installed them to C:\Windows\Symbols.

I insert C:\Windows\Symbols to File > Symbol File Path ... and _NT_SYMBOL_PATH.

0:000> .sympath
Symbol search path is: C:\Windows\Symbols
Expanded Symbol search path is: c:\windows\symbols

0:000> .reload
Reloading current modules

*** ERROR: Symbol file could not be found. Defaulted to export symbols for C:\Windows\system32\KERNELBASE.dll -

When opening an EXE I got some error messages:

*** ERROR: Symbol file could not be found. Defaulted to export symbols for ntdll.dll -

Did I miss anything? If I remember correctly, I didn't have such problems with XP.

Since the PDB is not being matched, it seems the symbols for your specific DLL version are missing (you probably applied some updates). You can instead use the MS symbol server to automatically download the matching PDB. Try this:

.symfix+ c:\symcache
!sym noisy
.reload /f
  • Oh dear! updates was the keyword. I installed unofficial Service Pack 2 several days ago and simply forgot it. That may cause these problems. – honeYmoon Mar 15 '17 at 11:39
