Running Win XP Media Center addition

After adding the program Photoshop to the "open with>" browse pull down
menu, I'm experiencing a change from the default setting. Now when I left
click on a picture to view it, I get a "not a valid Win 32 application"
message. I never saw this message before I added this program to the menu.
Is there a way to edit this menu and revert back to the original setting?

Any suggestions will be appreciated,

Don DeWitt
