ImageMagick-6.5.7 win32 installer env cleanup

[lexein]

Environment: Win XP Pro SP3, all updates
Installers:
ImageMagick-6.5.7-0-Q16-windows-dll.exe
ImageMagick-6.5.7-5-Q16-windows-dll.exe

These installers seem to have left the following in the System Path environment variable:
c:\program files\imagemagick-6.5.1-q8;

Is there a path search performed to clean out old directories?
If so, is that search case sensitive? That wouldn't match the path above...
Best practice might be
if an imagemagick path exists in the System Path,
and no matching folder exists,
remove the old path from the System Path.

Caveat:
It may be that the 6.5.1 uninstaller left it there...

A few releases ago we changed the script that sets and unsets the system path for install / uninstall. If the current version of the ImageMagick installer does not clean-up the path properly let us know and we will review the script. Thanks,
