[vtkusers] help!!!about vtkMDI

[zhao yong qiang]

Hi all,
I meet such a strange question.
I install vtk. My environment is VTK＋MSVC+WIN2000.
Then I follow the example of vtkMDI,
But in vtkOutputWindow.it showes:
 
ERROR: In C:\martink\vtk42\VTK\Rendering\vtkWin32OpenGLRenderWindow.cxx,
line 734
vtkWin32OpenGLRenderWindow (0x0148E248): wglCreateContext failed in
CreateAWindow(), error: 1114

but in disk C, there is not such directory.
Can someone help me?
Thanks!!!!
