[vtkusers] VTK installation problem

[Sarzynski, Melanie D]

I have been trying for a week to install VTK onto my Windows XP machine.  I 
downloaded tcl832.exe for TCL and installed it.  I then downloaded vtk42-
LatestRelease.exe.  The both use the standard WISE installation wizard.  The 
TCL install resulted in new icons on my Start Window, but the VTK didn't.  
When I try to test it out by clicking on an example file, I get an error:

can't find package vtk
while executing
"package require vtk"
(file "C:Program Filesvtk42
ExamplesVisualizationAlgorithmsTclColorIsosurface.tcl" Line 5)

I don't want to build either program from the source, but rather from the 
pre-compiled binaries.  I have tried setting the environment variable 
TCL_LIBRARY="C:/Program Files/Tcl/lib/tcl83.lib"

Any help is greatly appreciated!
