Out of the following three Windows binary installers, these are my results:
ImageMagick-6.6.4-10-Q16-windows-dll.exe - NO
ImageMagick-6.6.4-10-Q8-windows-x64-dll.exe - YES
ImageMagick-6.6.4-10-Q16-windows-x64-dll.exe - YES
Does anyone have any insight as to why the 32-bit version might not work? I'm testing this on a dual Intel Xeon E5530, 12 GB RAM, on Windows Server 2008 R2 64-bit.
