There are a number of ways to do this but the easiest is:
Goto Windows Explorer.
Find a file that you would wish to use with Photo Explorer - perhaps a BMP or GIF or JPG.
Right click and select "Open With"
Do NOT use one of the programs offered (even though Photo Explorer might be one of them) - instead use the browse option.
Finally make sure that you tick the box "Always use this program for this file type"
You will have to repeat this for the other file types.
