Sorry if this isn't the right place to post this. A reader of my
BF Digital Image Viewer article asked about a problem with Windows Photo Gallery. I don't know the answer, so I thought I'd better ask here. This is the message, which can be directly answered in the comments section on the original page if we get somebody to help:
'Windows Photo Gallery won't open my saved pictures. It says "file format is not supported." To fix this issue, I downloaded K-Lite Codec Pack. But once I try to install it, it says "error creating registry key: HKEY_CLASSES_ROOT" followed by various extensions (.3g2, mp4, .vob, etc.) So what do I do?'
