So after 4 hours I got it working:

You got Windows (x32 o x64) and IIS. You want PHP 5.5 and Imagemagick.

!! : Everything (PHP, Imagemagick installation, php_imagick.dll) needs to be x86 (32bit) for now (x64 builds are still experimental).

Tested and working:
Windows: 2008R2 x64 SP1
Visual C++ 2012 redist x86 and x64: http://www.microsoft.com/en-us/download ... x?id=30679  ---这个我没有安装，因为我电脑已经安装了Visual C++ 2012 开发环境了。
PHP 5.5: 
5.5.8 VC11 x86 Non Thread Safe (2014-Jan-09 18:16:08) ... all php5.5.x x86 nts should work ...
http://windows.php.net/downloads/releas ... 11-x86.zip
Imagemagick:
ImageMagick-6.8.4-0 Q16 x86 dll (you can try newer 6.8.4.x versions, but allways -x86-dll) ... install to c:\imagemagick and during install check "add to system path" ...
http://ftp.sunet.se/pub/multimedia/grap ... 86-dll.exe
php_imagick.dll :
get it from this site: http://www.peewit.fr/imagick/ :
version: Imagick for PHP 5.5.x, MSVC11 (Visual C++ 2012 Express), x86, Non Thread Safe, Build Date: Jul 9th, 2013 22:26:55 (CET), Download: php_imagick.dll (244 Kio)
http://www.peewit.fr/imagick/php55/vc11 ... magick.dll
