extension php_Imagick.dll not found in php.ini (2 replies)

My configuration is:
Wampserver 3.3.1 64 bit
Windows 7 64 bit
In Aestan PHP extensions says: The 'php_imagick.dll' extension file exists but there is no 'extension=php_imagick.dll' line in php.ini.
Finally I inserted this line in ALL PHP ini files, no positive result.
Anyone out there knowing this problem, I would be grateful, it is really time consuming!
