[Insight-users] Python Wrappers - WinXP

Hi Peter,

PATH needs to have the location of the ITK .dll files.  I have not
done this myself recently, but here is what another community member
sent me (I believe these are build directory locations instead of
installed locations):

set PATH=c:\Dhan\builds\ITK2\lib\Release;%PATH%
set PATH=c:\Dhan\builds\ITK2\lib;%PATH%
set PATH=c:\Dhan\builds\ITK2\bin\Release;%PATH%

HTH,
Matt
