Is there a difference between removing a program from add/remove programs in Control Panel verses the shortcut the program provides in the start menu?

Basically, I am getting a script error when I try to open the Add/Remove Programs control panel. I am using Internet Explorer version 6 and this is on Win2k Advanced Server with Serivce Pack 3.

It does not matter if the program, you want to remove, is not listed in Revo Uninstaller or in Windows Add/Remove Programs Control Panel applet.
