I installed it and it does not work. Anyone else had any joy with it?
It was the XP version I tried and I have just tried it again. When I open a photo folder and select thumbnails, I just get the CR2 icon, and when I double click on one Windows Picture and Fax viewer tries to open the file but errors out.
