i have Windows XP SP3 (x86) with WinDBG 6.11.0001.404 x86 - and it works fine. When I put MSEC.dll in winext directory '!load winext/MSEC.dll' returns:
The call to LoadLibrary(winext/MSEC.dll) failed, Win32 error 0n127
"The specified procedure could not be found."
Please check your debugger configuration and/or network access.
I have Visual Studio 12 using CRT 11 runtime libraries installed. Any clues/hints?
