I don't get the Preview Image on File Open

Hi ALl,

Can some one please help.

When I try to open a file, I don't get the preview image on the viewer window. 

I have selected Quick View and checked all the Option Settings but I cannot find a solution to this problem.

I am usin SW10 SP4.0

Thanks for your help.
