After you copy an image that is in a RAW file format to a computer that is running Windows Vista.

Cannot view Image Files from Camera

To resolve this problem, use one or more of the following methods, as appropriate for your situation: Obtain a RAW image codec

Obtain and install a Windows Vista-compatible RAW image codec from the camera manufacturer.
Obtain a RAW workflow program

Obtain and install a Windows Vista-compatible RAW workflow program that supports the camera model.

Note This does not resolve the issue in which you cannot view the images in Windows Photo Gallery. However, this action enables you to process the RAW image files. 
Save the images in a RAW + JPG format

If the camera has this option, configure the camera to save images in a RAW + JPEG format. This option frequently creates a separate JPEG image file together with the RAW image file. This action does not let you view the RAW image files. However, this action lets you view a JPEG representation of each RAW image file.
