ImageMagick commands path

I am on windows machine and installed apache web server for elgg. I have installed Imagemagickat "C:/Program Files/ImageMagick-6.6.5-Q16/"

While in tidypics configuration when I enter this path "C:/Program Files/ImageMagick-6.6.5-Q16/" where it asks for "Enter the path to your ImageMagick commands (with trailing slash)" and submit, it says "Unable to run ImageMagick. Please check the path."

What could be the correct path for imagemagick?

A prompt help is appreciated.

cheers
