I am using Wampserver 2.5 on my Windows 7 (32 bit) and my PHP version is 5.5.12. I am unable to use IMAGICK.
I have installed
I would add a small, but crucial advice, becaues it took me 10 hours of sunday, to get it working.
This is for Win7/10 x64 and Wamp 2.5 x64
There is a php.ini file in apache/bin folder and there should be added a new line with php_imagick.dll extension :)
