Adobe .pdf Thumbnails

[hhhiii]

I have recently updated to Vista X64 and when I installed Abobe reader, the preview thumbnails I used to get in Vista X86 no longer appeared. I there a registry fix for this problem?

I anyone is interested, for some reason if I opened Adobe reader and clicked on files to be opened, the thumbnail generated inside of the window and also inside of windows explorer. I guess the thumbnails had to be generated for the X64 program to work right.
