error adding ImageMagick dll in vs 2008

[Sashi]

Dim img As New ImageMagickObject.MagickImage
img = CreateObject("ImageMagickObject.MagickImage.1")

I had given the above codes in vb.net.

It returns the error while executing in another system - 'Retrieving the COM class factory for component with CLSID.....".

I had downloaded the dll - ImageMagick-6.7.3-6-Q16-windows-x64-dll.exe and included the reference in VS 2008.

In the configurartion manager also i had set the target as 'x86'.
Let me know on how to solve this issue.

thanks,
Sashi
