Files cannot be uploaded with ImageMagick

Hi!

This is somewhat urgent. I have been struggling to fix the problem of uploading the files (pdf/jpg) with thumbnails shown on.
I installed ImageMagick on windows at C:\ImageMagick and downloaded php_imagic at c:\xampp\php\ext\imagemagick, followed instruction from http://www.kobashicomputing.com/installing-imagemagick-with-php-and-windows, also took guidance from other sites. Finally Imagick module is uploaded on from php.

Alas! When my ImageMagick was not properly functioning, I could upload my files perfectly but without any thumbnails. but while IM is integrated (Though the Path at settings tab is still showing error), I cannot upload my files. Can someone throw some light on my problem? the error log is as following

First look at this makes me wonder if all of Imagemagick's files are installed and available to the web server. There's a message in that trace that this file C:\Users\Richa\.magick\IM_MOD_RL_JPEG_.dll' can't be opened, which makes me think it either isn't there, or that the web server doesn't have permissions to run it.

I don't understand why it is redirected to c:\users\richa\ when i have originally installed IM at c:\ImageMagick and the environment variable is also set to the same path. Also convert command runs well from c:\ImageMagick.
I m missing to set path somewhere. In the omeka settings it always shows error while i set payh to c:\ImageMagick

How to give server the permission to run it?
